Question 1092515: The length of a rectangle is 4 centimeters longer than its width. The area of the rectangle is 320 square centimeters. Find the width of the rectangle. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! width=w
length=w+4
area is w(w+4)=320
w^2+4w-320=0
(w+20)(w-16)=0
w=16 cm only positive root. ANSWER
length=20 cm
area is 16*20=320 cm^2
