The length of a rectangular banner is 2 feet longer than its width. If the area is 80 square feet, find the dimensions. Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! AREA=LW
L=W+2
80=(W+2)W
80=W^2+2
W^2+2-80=0

W-8=0
W=8 FEET FOR THE WIDTH.
L=8+2=10 FEET FOR THE LENGTH.
PROOF:
80=10*8
80=80
