# Perimeter of a Rectangle Formula

The sum of all the sides of a rectangle is known as the perimeter. Since the opposite sides of a rectangle are equal, so we just need to know the length and width to find the Perimeter of a Rectangle.

**Perimeter of a Rectangle Formula** is given as,

**\[\large Perimeter\;of\;a\;Rectangle=2(Length+Width)\]**

### Solved Examples

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

**Solution:**

Given,

Length = 9 cm

Width = 16 cm

Perimeter of Rectangle= 2(Length + Width)

= 2(9 + 16) cm

= 2 x 25 cm

= 50 cm

**Example: 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 + Width)

= 2(20 +9) cm

= 2 x 29 cm

= 58 cm

= 58 cm
