Perimeter of Rectangle is equal to twice of Sum of its length and breadth.

Perimeter of Rectangle Formula = 2 ( Length of Rectangle + Breadth of Rectangle )

## Perimeter of Rectangle Examples

**Find the perimeter of a rectangle in which:**

**Example 1**

length = 12 cm and breadth = 5 cm

**Explanation:**

Given:

Length = 12 cm

Breadth = 5 cm

Perimeter of Rectangle = 2 ( l + b ) units

= 2 ( 12 + 5 ) cm

= ( 2 x 17 ) cm

= 34 cm

**Example 2**

length = 7 cm and breadth = 11 cm

**Explanation:**

Given:

Length = 7 cm

Breadth = 11 cm

Perimeter of rectangle = 2 ( l + b ) units

= 2 ( 7 + 11 ) cm (Here, Length = 7 cm , Breadth = 11 cm )

= ( 2 x 18 ) cm

= 36 cm

**Example 3**

length = 25 cm and breadth = 12 cm

**Explanation:**

Given:

Length = 25 cm

Breadth = 12 cm

Perimeter of rectangle = 2 ( l + b ) units

= 2 ( 25 + 12 ) cm (Here, Length = 25 cm , Breadth = 12 cm )

= ( 2 x 37 ) cm

= 74 cm

**Example 4**

length = 21 cm and breadth = 7 cm

**Explanation:**

Given:

Length = 21 cm

Breadth = 7 cm

Perimeter of rectangle = 2 ( l + b ) units

= 2 ( 21 + 7 ) cm (Here, Length = 21 cm , Breadth = 7 cm )

= ( 2 x 28 ) cm

= 56 cm

**Example 5**

length = 16 cm and breadth = 9 cm

**Explanation:**

Given:

Length = 16 cm

Breadth = 9 cm

Perimeter of rectangle = 2 ( l + b ) units

= 2 ( 16 + 9 ) cm (Here, Length = 16 cm , Breadth = 9 cm )

= ( 2 x 25 ) cm

= 50 cm
