Question 301891: A rectangular board is 8 inches longer than it is wide. If the area of the board is 48 square inches, find the length and the width Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let the width be x inches
the length is x+8
Area of rectangle = L * W
x(x+8)=48
x^2+8x=48
x^2+8x-48=0
x^2+12x-4x-48=0
x(x+12)-4(x+12)=0
(x+12)(x-4 ) = 0
x= -12 Or 4
So width = 4 inches
Length =12 inches
