Question:

The area of a rectangle is $a^2 - b^2 $ and its length is a + b, what will be its breadth ?

Options:

2ab

a + b

ab

a - b

Correct Answer:

a - b

Explanation:

We know that,

Area of a rectangle = Length × Breadth

a2 - b2 = (a + b)(a - b)

Given,

The area of a rectangle is a2 - b2 = (a + b)(a - b)

Its length is a + b

= a2 - b2 = (a + b)(a - b)

= (a + b) × Breadth

= (a + b)(a - b) = (a + b) × Breadth

= Breadth = (a - b)
