Look at these polygons. Copy and complete the table. Rectangle 40 + 40 + 30 + 30

Polygon (a) has six sides, so it is a hexagon. The side lengths are 3 m, 2 m, 3 m, 3 m, 2 m, and 3 m.
The perimeter is the sum of all its side lengths.

$$\text{Perimeter (a)} = 3\, \text{m} + 2\, \text{m} + 3\, \text{m} + 3\, \text{m} + 2\, \text{m} + 3\, \text{m}$$ $$\text{Perimeter (a)} = 16\, \text{m}$$

Polygon (b) has four sides with lengths 4 m, 4 m, 5 m, and 5 m. This is a kite.
The perimeter is the sum of all its side lengths.

$$\text{Perimeter (b)} = 4\, \text{m} + 4\, \text{m} + 5\, \text{m} + 5\, \text{m}$$ $$\text{Perimeter (b)} = 18\, \text{m}$$

Polygon (c) has three sides, so it is a triangle. The side lengths are 7 m, 8 m, and 3 m.
The perimeter is the sum of all its side lengths.

$$\text{Perimeter (c)} = 7\, \text{m} + 8\, \text{m} + 3\, \text{m}$$ $$\text{Perimeter (c)} = 18\, \text{m}$$
