Math Problem Statement
The length of a rectangular garden is 10 meters longer than its width. If the garden's perimeter is 204 meters, what is the area of the garden in square meters?
Solution
Let's denote the width of the garden as meters. According to the problem, the length is 10 meters longer than the width, so the length can be expressed as meters.
The formula for the perimeter of a rectangle is:
Given that the perimeter is 204 meters, we substitute the values:
Simplifying:
Subtract 20 from both sides:
Now, divide by 4:
So, the width of the garden is 46 meters. The length is meters.
Now, we can calculate the area of the garden using the formula for the area of a rectangle:
Thus, the area of the garden is 2576 square meters.
