Question 1130872: the area of the rectangular book shelf is 28 square feet. the length is 2 feet longer than the width. what are the dimensions of the book shelf to the nearest tenth? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! width=x
length=x+2
x(x+2)=28
x^2+2x-28=0
x=(1/2)(-2+/- sqrt(4+112)); sqrt (116)=10.77
x=8.77*1/2=4.4 only positive root
width is 4.4 feet
length is 6.4 feet 28.16 ft^2
