Answers:

1. Perimeter of a triangle = 3 + 4 + 5 = 12 cm

2. Perimeter of a square = 40 m (given)

Length of each side = 40 / 4 = 10m

3. Perimeter = 4 x side = 4 x 200 = 800 m

Cost of fencing = 800 x 20 = Rs 16000

4. Perimeter = 20 cm (given)

Length of each side of a square = 20 / 4 = 5 cm

5. Length of each side of a square = 6m (given)

Area of a square plot = side x side = 6 x 6 = 36 square m

6. Area of a rectangle = length x breadth

Length = 10 cm
Breadth = 8 cm
Area = 10 x 8 = 80 square cm

7. Area of a rectangular garden = 42 square cm and length = 7 cm (given).

Area = l x b
Breadth = Area / length = 42 / 7 = 6 cm.

8. Area of a rectangle = l x b

Length =5 cm and breadth = 3 cm (given)
Area = 3 x 5 = 15 square cm

9. Area of a square carom board = 64 square cm

Length of each side = 64/4 = 16 cm

10. Area of a rectangular garden = 330 sq cm

Breadth = 15 cm (given)
Length = Area / Breadth = 330/15 = 22 cm.
