A rug is shaped like a rectangle whose perimeter is 112 ft. The length is 3 times as long as width. Find the length and the width.
=================================
P = 2W + 2L = 112
W + L = 56
-----------
W + L = 56
L = 3W

L = 3W
2L + 2W = 112 ft
�
Subs top eqn into bottom:
2(3W) + 2W = 112
8W = 112
W = 14 �> L = 3(14) = 42
�
Ans: ft and ft
==
Check: 2(14) + 2(42) = 28 + 84 = 112 (ok)
