Question

The length of a rectangle exceeds its width by 5 inches and the area is 150 square inches what are the length and the width of the rectangle

Answer 1

L = w+5

150= L x w

150=(w+5) x w

150 = w^2+5w

w^2+5w-150 = 0

(w+15)(w-10) = 0

(w-10)=0 w = 10

l = 10 + 5 = 15

10 x 15 = 150

length is 15, width is 10
