## What is the Perimeter of a Rectangle?

The perimeter of a rectangle is equal to the total length of the boundary.

Let ABCD be a rectangle whose length be l and breadth be b.

Perimeter = Length of the boundary

= AB + BC + CD + DA

= 2 x AB + 2 x BC

= 2 ( AB + BC )

= 2( length + breadth)

**Perimeter of Rectangle = 2(l + b) unit**

### Rectangular Perimeter Formula

### Examples: Find the Perimeter of Rectangle

##### (a) l = 38 m and b = 22 m

Perimeter of Rectangle = 2(l + b) = 2( 38 + 22)

= 2(60) = 120 m.

##### (b)bl = 30 m and b = 20 m

Perimeter of Rectangle = 2(l + b) = 2( 30 + 20)

= 2(50) = 100 m.
