# Perimeter of a Rectangle Formula

In this article, we will discuss theÂ perimeter of a rectangle in detail along with its rectangle perimeter formula and a few solved examples. We know that the perimeter of any two-dimensional shape is equal to the total distance covered by the boundary of the given shape.

## Perimeter of a Rectangle

The perimeter of a rectangle is defined as the sum of all the sides of a rectangle. For any polygon, the perimeter formulas are the total distance around its sides. In case of a rectangle, the opposite sides of a rectangle are equal and so, the perimeter will be twice the width of the rectangle plus twice the height of the rectangle and it is denoted by the alphabet “p”

## Perimeter of a Rectangle Formula

The perimeter of rectangle formula is given by

The perimeter of a rectangle, p = 2 ( l+b) units

where

“l” is the length of the rectangle

“b” is the breadth of the rectangle

### Solved Examples

Example 1:Â Find the perimeter of a rectangle whose length is 9 cm and width is 16 cm.

Solution:

Given,

Length = 9 cm

Width = 16 cm

Perimeter of Rectangle= 2(Length + Breadth)

= 2(9 + 16) cm

= 2 x 25 cm

Therefore, the perimeter of a rectangle= 50 cm

Example 2: Find the perimeter of a rectangle whose length and width is 20 cm and 9 cm respectively.

Solution:

Given,

Length = 20 cm

Width = 9 cm

Perimeter of Rectangle = 2(Length + Breadth)

= 2(20 +9) cm

= 2 x 29 cm

Therefore, the perimeter of a rectangle = 58 cm
