Question 312109: The area of a rug is 66 square feet. The length of the rug is 5 feet longer than the width. What is the width of the rug? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! L=W+5
Area=LW
66=(W+5)W
66=W^2+5W
W^2+5W-66=0
(W+11)(W-6)=0
W-6=0
W=6 ANS. FOR THE WIDTH.
L=6+5=11 ANS. FOR THE LENGTH.
PROOF:
66=6*11
66=66
