Question

the length and breadth of a rectangle is (x+1)and(x-1) respectively. find its area






​

Answer 1

It's area would be the length times breadth,

I.e.

(x+1)×(x-1)

= x^2 - 1

Answer 2

Area of rectangle = length × breadth
Given,
Length = (x+1)
Breadth = (x-1)
Area = (x+1) (x-1)
= x^2 -1

Area of the rectangle = x^2 - 1
