Question 375523: the area of a rectangle is the product of its lenght and width, and equals 1062. If the lenght is 5 more then three times the width, find the width of the rectangle? Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! L=3W+5
AREA=LW
1062=(3W+5)W
1062=3W^2+5W
3W^2+5W-1062=0
(3W+59)(W-18)=0
W-18=0
W=18 ANS. FOR THE WIDTH.
L=3*18+5
L=54+5
L=59 ANS. FOR THE LENGTH.
PROOF:
1062=18*54
1062=1062
