Question 644510: a rug has a primeter of 320 feet. the length is 7 times longer than the width, find the length and width
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
P = 2L + 2W
320 = 2L + 2W
320 = 2(7W) + 2W
320 = 14W + 2W
320 = 16W
320/16 = W
20 = W
W = 20
L = 7W
L = 7*20
L = 140
So the length is 140 feet and the width is 20 feet
