Introduction

Understanding the Relationship Between Width and Length of a Rectangle

When it comes to a rectangle with a constant area, the relationship between its width and length is crucial. The area of a rectangle is calculated by multiplying its width and length. In this article, we will explore the possible combinations of width and length of a rectangle with a constant area, as shown in the table below.

Width vs. Length of a Rectangle

Width (w)	Length (l)
2	37.5
4	18.75
6	12.5

The Relationship Between Width and Length

As we can see from the table, the width and length of the rectangle are inversely proportional to each other. This means that as the width increases, the length decreases, and vice versa. This relationship is a direct result of the constant area of the rectangle.

Calculating the Area of a Rectangle

The area of a rectangle is calculated by multiplying its width and length. Mathematically, this can be represented as:

Area = Width × Length

In the case of the rectangle with a constant area, we can use this formula to calculate the area for each combination of width and length.

Example 1: Width = 2, Length = 37.5

Using the formula above, we can calculate the area of the rectangle with a width of 2 and a length of 37.5:

Area = 2 × 37.5 Area = 75

Example 2: Width = 4, Length = 18.75

Using the formula above, we can calculate the area of the rectangle with a width of 4 and a length of 18.75:

Area = 4 × 18.75 Area = 75

Example 3: Width = 6, Length = 12.5

Using the formula above, we can calculate the area of the rectangle with a width of 6 and a length of 12.5:

Area = 6 × 12.5 Area = 75

Conclusion

In conclusion, the table above shows the possible combinations of width and length of a rectangle with a constant area. The relationship between the width and length is inversely proportional, meaning that as the width increases, the length decreases, and vice versa. This relationship is a direct result of the constant area of the rectangle. By using the formula for calculating the area of a rectangle, we can confirm that each combination of width and length results in the same area of 75.
