The area of a rectangle is $a^2 - b^2 $ and its length is a + b, what will be its breadth ?
Answer & explanation
Correct answer: option 4
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)
