Question

The length of a rectangle is 4 ft longer than it’s width. If the perimeter of the rectangle is 28 ft, find it’s area.

Answer 1

Answer: 45 ft 2

Explanation:

L = W + 4

P = 2(W + L)

28 = 2(W + W + 4)

14 = 2W + 4

2W = 10

W = 5

L = W + 4 = 5 + 4 = 9

A = L x W

A = 9 x 5

A = 45

A = 45 ft 2
