Question

The length of a rectangular garden is 10 feet longer than its width. The garden's perimeter is 188 feet. Find the length of the garden.

Answer 1

Let length  = x, then the width = x-10


Perimeter = 2L + 2W

188 = 2x + 2(x - 10)

188 = 2x + 2x - 20

4x = 208

x = 52  

The length is 52 ft.
