Perimeters of Triangles and Quadrilaterals

The Perimeters of Triangles and Quadrilaterals

Find the perimeters of triangles and quadrilaterals

Perimeter β is defined as the total length of a closed shape. It is obtained by adding the lengths of the sides inclosing the shape. Perimeter can be measured in ππ , ππ ,ππ ,π,ππ e. t. c

Examples

Example 1

Find the perimeters of the following shapes

**Solution**

- Perimeter = 7π + 7π + 3π + 3π = 20 π
- Perimeter = 2π + 4π + 5π = 11 π
- Perimeter = 3ππ + 6ππ + 4ππ + 5ππ + 5 ππ + 4ππ = 27 ππ
