Question 804801: The length of a rectangle is 3ft more than 5 times its width. If the perimeter is 54ft, what are the dimensions? Answer by erica65404(394) (Show Source):
You can put this solution on YOUR website! L=5W+3
P=2L+2W
54=2L+2W
plug in L
54=2(5W+3)+2W
54=10W+6+2W
54=12W+6
48=12W
W=4
plug W into L=5W+3
L=5(4)+3
L=23
The length is 23ft and the width is 4ft
