Question 306001: the length of a rectangular picture is 11 cm less than its width. The area of the picture is 12cm squared find the demensions of the picture Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! AREA=12 CM^2
AREA=LW
L=W-11
12=(W-11)W
12=W^2-11W
W^2-11W-12=0
(W-12)(W+1)=0
W-12=0
W=12 CM. ANS. FOR THE WIDTH.
L=12-11=1 CM.ANS. FOR THE LENGTH.
PROOF:
12=12*1
12=12
