Question

Eric’s garden is in the shape of a rectangle. The length is 10 feet less than twice the width, and the perimeter is 160 feet. Find the length of the garden.

Answer 1

length = 50

Explanation:

let width = w and length = 2w - 10

Perimeter of a rectangle is 2(L+W)

2(2w - 10 + w) = 160

4w - 20 + 2w = 160

6w = 180

w = 30

The length is 10 feet less than twice the width

2w - 10

2(30) - 10

60 - 10 = 50
