Question 1071357: the length of a rectangle is 8 feet less than twice the width. the perimeter is 38 feet. how long is each side? Answer by ikleyn(52879) (Show Source):
L = 2W - 8.
The "perimeter equation" is
L + W + L + W = 38, or
(2W-8) + W + (2W-8) + W = 38,
6W - 16 = 38 ---> 6W = 38 + 16 = 54 ---> W = = 9.
Answer. W = 9, L = 2W-8 = 2*9-8 = 10.
