Length

Calculating the perimeter of plane shapes

A perimeter is the total distance round a shape. The total distance covered by an object is referred to as the perimeter.

The formula for the perimeter is 2(L+B)

L: Length and B : Breadth

Examples

Calculate the perimeter of the following :

1. Length 4cm and breadth 7cm

2. Length 6cm and breadth 4cm

Solutions

1. 2( L+B)

2(4+7)= 2(11) =22cm

2. 2(L+B)

2(6+4)= 2(10)= 20cm

Evaluation: Teacher ask questions as regards the topic.
