In the realm of geometry, rectangles stand as fundamental shapes, their properties and relationships captivating mathematicians and enthusiasts alike. This article delves into an intriguing problem concerning rectangles: how does the area of a rectangle change when its perimeter undergoes a specific increase? We embark on a journey to unravel this relationship, employing mathematical principles and logical reasoning to arrive at a comprehensive solution.

Problem Statement: Decoding the Rectangle's Transformation

The problem at hand presents us with a rectangle where one side is three times the length of the other side. This initial condition sets the stage for our investigation. The crux of the problem lies in what happens when the rectangle's perimeter experiences a 2% increase. Our mission is to determine the corresponding percentage increase in the rectangle's area. This problem elegantly combines the concepts of perimeter and area, prompting us to explore their interdependence and how they respond to changes in dimensions.

Setting the Stage: Defining Variables and Establishing Relationships

To tackle this problem effectively, we introduce variables to represent the rectangle's dimensions. Let's denote the shorter side of the rectangle as x and the longer side as 3x, adhering to the problem's initial condition. With these variables in place, we can express the perimeter and area of the rectangle in terms of x. The perimeter, being the total length of all sides, is given by 2(x + 3x) = 8x. The area, defined as the product of length and width, is expressed as x * 3x = 3x². These expressions form the foundation for our analysis.

Perimeter Expansion: Quantifying the Change

The problem states that the perimeter of the rectangle increases by 2%. This increase directly impacts the value of x, as the perimeter is directly proportional to x. To quantify this change, we introduce a new variable, x', to represent the shorter side of the rectangle after the perimeter increase. The new perimeter is 1.02 times the original perimeter, which translates to 1.02 * 8x = 8.16x. The new perimeter can also be expressed in terms of x' as 8x'. Equating these two expressions, we get 8x' = 8.16x, which simplifies to x' = 1.02x. This equation reveals that the shorter side of the rectangle increases by 2% as well.

Area Transformation: Unveiling the Percentage Increase

With the new value of x determined, we can calculate the new area of the rectangle. The longer side of the rectangle after the perimeter increase is 3x' = 3 * 1.02x = 3.06x. The new area, denoted as A', is then given by x' * 3x' = 1.02x * 3.06x = 3.1212x². To determine the percentage increase in area, we compare the new area A' with the original area A. The percentage increase is calculated as [(A' - A) / A] * 100. Substituting the expressions for A' and A, we get [(3.1212x² - 3x²) / 3x²] * 100 = 4.04%. This result reveals that the area of the rectangle increases by 4.04% when the perimeter increases by 2%.

Unraveling the Connection: Perimeter, Area, and Percentage Increase

Our analysis has demonstrated a clear relationship between the percentage increase in the perimeter and the percentage increase in the area of the rectangle. When the perimeter increases by 2%, the area increases by 4.04%. This difference arises from the fact that the area is proportional to the square of the side length, while the perimeter is directly proportional to the side length. Consequently, a percentage change in the side length has a more pronounced effect on the area than on the perimeter.

Key Takeaways: Insights into Rectangle Transformations

This problem provides valuable insights into the behavior of rectangles under dimensional changes. We have learned that:

• A change in the perimeter of a rectangle directly influences its side lengths.
