Question 950609: the perimeter of a rectangle is 65 inches the ration of the length to the width is 4:1 what is the length and the 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 in=2(4W+W)
65 in=8W+2W
65 in=10W Divide each side by 10
6.5 in=W ANSWER 1: Width is 6.5 inches.
L=4W=4(6.5 in)=26 in ANSWER 2: Length is 26 inches.
CHECK
P=2(L+W)
65 in=2(26in+6.5in)
65 in=2(32.5 in)
65 in=65 in
