The width of a rectangle is 2 inches shorter than the length and the perimeter is 80. Set up an equation for the perimeter involving only L, the length.Find the width as well.

Perimeter = 2L + 2W = 2L + 2(L2)
= 4L  4 = 80
L = 21
W = L2 = 19

Perimeter=2L+2W=2L+2(L2)
= 4L4 =80
L = 21
W = L2 = 19

Why do you repeat posted answers? They are being sent back to this website, not to your school that assigned the question.
