Question

A rectangle is 2 feet longer than it is wide. If the area is 8 square feet, find its perimeter.

.....Ft

Answer 1

12 feet

Explanation:

w = width

w+2 = length

w(w+2) = 8

w² + 2w - 8 = 0

(w+4)(w-2) = 0

w = -4 exclude because a length cannot be negative

w = 2

length = 2+2 or 4

P = 2(2)+2(4)

P = 4+8 or 12
