Question

The length of a rectangle is 3 meters more than its width. If the area is 108 square meters, what are the length and width?

Answer 1

x = y+3
x = length
y = width

(y+3)(y) = 108

y^2 +3y -108 = 0

y = 9
x = 12

Answer 2

let breadth be x m then length is x+3m

x(x+3)=108

x^2+3x=108
solving this equation we get breadth(x)=9 and length(x+3)=12
