Question

The length of a rectangle is 8 more than the width. The area is 825 square inches. Find the length and width of the rectangle

Answer 1

 

Let width be x then

Length is x+8

Therefore area which is given by L*W will be

Area=x*(x=8)

But area =825 sq inches

x*(x+8)=825

x^2+8x-825=0

we use quadratic formula to solve this

and get our x=25 therefore

our width is 25

and length is 33
