Question

A certain rectangles length is 1 feet longer than its width. if the area of the rectangle is 110 square ft, find its dimensions

Answer 1

let width= x
so, length=x+1

area= length x breadth = x(x+1)=110
or, x^2+x-110=0

x=10 or -11

since x represents dimension it cannot be negative.So, x=10

so width=10 and length=11.

So it was 10 ft by 11 ft

Hope this helps! :D
