#h2
To find the area of the lawn, we will use the given total cost of grassing and the cost per square meter. We'll then use this area to calculate the side length of the square lawn.
Calculating the Area
#h3
To accurately determine the area of the square lawn, we utilize the information provided about the total cost of grassing and the cost per square meter. Specifically, the total cost of grassing the lawn is given as ₹72037.35, and the cost per square meter is ₹1.35. The fundamental principle here is that the total cost is the product of the area and the cost per unit area. Therefore, to find the area, we need to divide the total cost by the cost per square meter. This can be represented mathematically as: Area = Total Cost / Cost per Square Meter. By substituting the given values into this formula, we get Area = ₹72037.35 / ₹1.35. Performing this division will yield the area of the lawn in square meters. This step is crucial because it directly links the financial aspect of the grassing project to the physical dimensions of the lawn. The result of this calculation not only provides a quantitative measure of the lawn's size but also serves as a foundation for further calculations, such as determining the side length of the square lawn and, subsequently, the perimeter. The precision of this calculation is paramount as it ensures that all subsequent steps are based on an accurate representation of the lawn's size. This methodical approach to finding the area exemplifies the practical application of mathematical principles in real-world scenarios, particularly in landscaping and home improvement projects. By understanding and applying this calculation, homeowners and landscaping professionals can effectively estimate and manage the costs associated with grassing a lawn.
Area = Total Cost / Cost per m²
Area = ₹72037.35 / ₹1.35 = 53361 m²
Finding the Side Length
#h3
Having accurately calculated the area of the square lawn, the next logical step is to determine the length of one side of the square. This is a crucial step as it provides a direct measure of the lawn's dimensions and is essential for calculating the perimeter, which in turn is needed to determine the fencing cost. Since the lawn is square, all sides are of equal length, and the area of a square is given by the formula Area = side². To find the side length, we need to reverse this formula by taking the square root of the area. Mathematically, this can be represented as: Side = √Area. In the previous step, we calculated the area to be 53361 square meters. Therefore, to find the side length, we take the square root of 53361. This calculation will give us the length of one side of the square lawn in meters. The precision of this calculation is vital as it directly impacts the accuracy of the perimeter calculation and, consequently, the total fencing cost. Furthermore, understanding how to derive the side length from the area of a square is a fundamental mathematical concept with broad applications beyond this specific problem. It illustrates the inverse relationship between squaring a number and taking its square root, a concept that is widely used in various fields of mathematics and science. This step not only solves a practical problem related to lawn dimensions but also reinforces a key mathematical principle. By accurately finding the side length, we ensure that all subsequent calculations are based on a solid foundation, leading to a reliable estimate of the fencing cost.
Side = √Area
Side = √53361 m² = 231 meters
Calculating the Fencing Cost
#h2
Now that we know the side length, we can calculate the perimeter of the lawn and then the total cost of fencing it twice.
Determining the Perimeter
#h3
The determination of the perimeter is a pivotal step in calculating the total cost of fencing the square lawn. The perimeter, which is the total length of the boundary of the lawn, is essential for understanding how much fencing material will be required. For a square, the perimeter is simply four times the length of one side. This is because a square has four equal sides, and the perimeter is the sum of the lengths of all sides. Mathematically, the formula for the perimeter of a square is given by: Perimeter = 4 × Side. In the previous section, we calculated the side length of the square lawn to be 231 meters. Therefore, to find the perimeter, we multiply this side length by 4. This calculation will give us the total length of the boundary of the lawn in meters. The accuracy of this calculation is crucial as it directly impacts the estimation of the amount of fencing material needed and, consequently, the total cost of the fencing project. A precise perimeter calculation ensures that there is neither an underestimation, which could lead to a shortage of materials, nor an overestimation, which could result in unnecessary expenses. Furthermore, understanding how to calculate the perimeter of a square is a fundamental geometric concept with wide-ranging applications in various fields, including construction, landscaping, and urban planning. This step not only provides a practical solution for the specific problem of fencing a lawn but also reinforces a key mathematical principle. By accurately determining the perimeter, we set the stage for a reliable calculation of the total fencing cost, ensuring that the project can be planned and executed efficiently and cost-effectively.
Perimeter = 4 × Side
Perimeter = 4 × 231 meters = 924 meters
Calculating the Total Fencing Length
#h3
After determining the perimeter of the square lawn, the next critical step is to calculate the total fencing length required. This is particularly important in our scenario because the lawn needs to be fenced twice with wire. Fencing a lawn twice essentially means that we need to cover the entire perimeter two times over, providing enhanced security and a more robust barrier. To calculate the total fencing length, we simply multiply the perimeter of the lawn by the number of times it needs to be fenced. In this case, the perimeter, which we calculated to be 924 meters, needs to be multiplied by 2. Mathematically, this can be represented as: Total Fencing Length = Perimeter × Number of Fencings. By substituting the values, we get Total Fencing Length = 924 meters × 2. This calculation will give us the total length of wire required to fence the lawn twice. The accuracy of this calculation is paramount as it directly influences the total cost of the fencing project. An accurate estimate of the total fencing length ensures that we purchase the correct amount of wire, avoiding shortages or wastage. Furthermore, this step highlights the practical application of basic multiplication in real-world scenarios. It underscores the importance of understanding the problem context and applying the appropriate mathematical operations to arrive at a solution. By precisely calculating the total fencing length, we ensure that the subsequent cost calculation is reliable, allowing for effective budgeting and planning of the fencing project. This step not only addresses the specific problem at hand but also reinforces the broader relevance of mathematical skills in everyday life.
Total Fencing Length = Perimeter × 2
Total Fencing Length = 924 meters × 2 = 1848 meters
Determining the Final Fencing Cost
#h3
The final step in our calculation process is to determine the final fencing cost, which is a crucial figure for budgeting and planning the fencing project. This cost is calculated by multiplying the total fencing length by the cost per meter of the wire. We have already calculated the total fencing length required to fence the lawn twice, which is 1848 meters. The cost of the wire is given as ₹2.85 per meter. To find the total cost, we simply multiply the total fencing length by the cost per meter. Mathematically, this can be represented as: Total Fencing Cost = Total Fencing Length × Cost per Meter. By substituting the values, we get Total Fencing Cost = 1848 meters × ₹2.85 per meter. Performing this multiplication will give us the total cost of fencing the lawn twice. This calculation is the culmination of all the previous steps, and its accuracy depends on the precision of each preceding calculation, from determining the area and side length of the lawn to calculating the perimeter and total fencing length. The final fencing cost provides a concrete financial figure that homeowners and landscaping professionals can use to make informed decisions about the project. It allows for a clear understanding of the investment required and facilitates effective cost management. Furthermore, this step demonstrates the practical application of multiplication in financial calculations, reinforcing the importance of mathematical skills in everyday economic activities.
