✅ Answer Key

Part 1: Rectangular Survival Shelters

1. Perimeter = 2(4 + 3) = 2(7) = 14 metres

2. Perimeter = 2(8 + 6) = 2(14) = 28 metres

3. Perimeter = 2(5.5 + 2.8) = 2(8.3) = 16.6 metres

4. Perimeter = 2(3.2 + 4.7) = 2(7.9) = 15.8 metres

5. Perimeter = 2(2.4 + 1.8) = 2(4.2) = 8.4 metres

Part 2: Triangular Structures

6. Perimeter = 4 + 5 + 6 = 15 metres

7. Perimeter = 2.5 + 3.2 + 4.1 = 9.8 metres

8. Perimeter = 7 + 7 + 7 = 21 metres

9. Perimeter = 3.8 + 4.2 + 5.5 = 13.5 metres

10. Perimeter = 4.5 + 4.5 + 6 = 15 metres

Part 3: Irregular Survival Shapes

11. Perimeter = 8 + 6 + 7 + 9 + 5 = 35 metres

12. Perimeter = 3.5 + 4.2 + 2.8 + 5.1 + 3.9 = 19.5 metres

13. Perimeter = 6 × 12 = 72 metres

14. Perimeter = 8 × 4 = 32 metres

15. Perimeter = 15 + 12 + 18 + 14 = 59 metres

Part 4: Multiple Choice

16. 20 metres (4 × 5 = 20)

17. 2 × (Length + Width)

18. 24 metres (6 + 8 + 10 = 24)

Part 5: Word Problems

19. Perimeter = 2(12 + 8) = 40 metres of rope needed

20. Perimeter = 15 + 12 + 18 + 14 + 16 + 13 = 88 metres. Knowing perimeter helps with resource planning, security planning, and material requirements.
