Perimeter of a Rectangle Formula

The perimeter of a rectangle is explained here along with its formula and a few solved examples. The key points that are covered here include the perimeter of a rectangle definition, formula, and know how to find the perimeter of a rectangle with solved examples.

Perimeter of a Rectangle Definition

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.

How to Find the Perimeter of a Rectangle?

To find the perimeter of a rectangle, just add all the sides. 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.

Solved Examples – Perimeter of Rectangle

Example 1: 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 + Width)

= 2(9 + 16) cm

= 2 x 25 cm

= 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 + Width)

= 2(20 +9) cm

= 2 x 29 cm

= 58 cm
