ANSWERS:

1. 24 cm
2. 4 cm
3. Perimeter
4. 15 sq cm
5. 9 sq cm
6. 9m
7. Area
8. Square cm/m/km
9. 20 cm
10. 3 cm
11. Perimeter of a square = 100m
    Length of side of the wall = 100/4 = 25m
    Area = Side X Side = 25 x 25 = 625 sq m
12. Length = 150m
    Breadth = 50m
    Perimeter = 150 + 50 + 150 + 50 = 400m
13. Perimeter of a square = 420 cm
    Length of each side = 420/4 = 105 cm
14. Length = 12 cm
    Breadth = 9 cm
    Perimeter = 12 + 9 + 12 + 9 = 42 cm
15. Length = 48m
    Breadth = 20m
    Perimeter = 48 + 20 + 48 + 20 = 136m
    Cost of fencing = 136 x 50 = 6800 rupees
