Answer 2

(2p + 2r) expression represents the perimeter of the rectangle.

The correct option is D )

D ) 2p + 2r

Explanation:

Given:

Let p be the Length of Rectangle

Let r be the Width of Rectangle

To Find:

Perimeter of Rectangle = ?

Solution:

Perimeter of Rectangle:

Sum of Twice Length and Twice Width,

i.e

`\textrm{Perimeter of Rectangle}=2* Length + 2* Width`

So we will have

`\textrm{Perimeter of Rectangle} =2p+2r......................as\ required`

(2p + 2r) expression represents the perimeter of the rectangle.

The correct option is D )

D ) 2p + 2r
