Question 656843: the length of a rectangle is three less than twice the width and its equal to 44 sq. cm .find the dimension of rectangle. Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! L=2W-3
PERIMETER=L*W
44=(2W-3)W
44=2W^2-3W
2W^2-3W-44=0
(2W-11)(W+4)=0
2W-11=0
W=11/2
W=5.5 ANS. FOR THE WIDTH.
L=2*5.5-3
L=11-3
L=8 ANS. FOR THE LENGTH.
PROOF:
44=8*5.5
44=44
