The length of a rectangle is 7 inches more than it's width. If the perimeter of the rectangle is 66 inches, find it's dimensions

Answer 1

Hello Savannah

L = 7 + W

P = 2(L + W)

Substitute L = 7 + W in the perimeter equation, you get

P = 2(7 + W + W) = 66

14 + 4W = 66

4W = 52

W = 52 / 4 = 13 in

L = 7 + W = 7 + 13 = 20 in
