Perimeter
- Perimeter is the distance around the edge of a shape.
- Perimeter can be defined as the path or the boundary that surrounds a shape. It can also be defined as the length of the outline of a shape.
1. Perimeter = 2 (25 + 10)
= 2 (35) = 70 cm
2. Perimeter = 15 + 20 2(16)
= 35 + 32 = 67 cm
3. Perimeter = 12 + 20 + 18 = 50 cm
4. Perimeter = 2(8 + 15) = 2(23) = 46 cm
