Question 950915: If a rectangle has a perimeter of 65 feet and the length is four times as long as the width. How long is the length and width? Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! W=width; L=length=4W; P=perimeter=65 inches
P=2(L+W) Substitute for L.
65 ft=2(4W+W)
65 ft=8W+2W
65 ft=10W Divide each side by 10
6.5 ft=W ANSWER 1: Width is 6.5 feet.
L=4W=4(6.5 ft)=26 feet ANSWER 2: Length is 26 feet.
CHECK
P=2(L+W)
65 ft=2(26ft+6.5ft)
65 ft=2(32.5 ft)
65 ft=65 ft
