Question

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

Answer 1

Area of rectangle = I * B

A =(x +1) (x - 1 ) = x square - 1

Answer is x square - 1

Answer 2

Its area is $x^2-1$

Step-by-step explanation:

Length of rectangle = (x+1)

Breadth of rectangle = (x-1)

Area of rectangle =$Length \times Breadth$

Area of rectangle =$(x+1) \times (x-1)$

Area of rectangle =$x(x-1)+(x-1)$

Area of rectangle =$x^2-x+x-1$

Area of rectangle =$x^2-1$

Hence Its area is $x^2-1$
