14. A piece of string 80cm long is bent to form a regular pentagon. Find the length of each side?
15. Find the length of each side of a regular hexagon of perimeter 36m?

1. Area of a square = Side x Side = 25 x 25 = 625 sq. cm
2. Perimeter of an equilateral triangle = 3 x side = 3 x 8 = 24 cm
3. Area of a rectangle = l x b = 20 x 5 = 100 sq. cm
4. Area of a square = Side x Side = 7 x 7 = 49 sq. m
5. Perimeter = 6 + 6 + 8 = 20cm
6. Perimeter = 20 cm
Sum of the lengths of two sides = 6 + 8 = 14cm
Length of third side = 20 – 14 = 6cm
7. Perimeter = 2 x (l + b) = 2 x (50 + 30) = 2 x 80 = 160m
Cost of fencing = 160 x 24 = 3840 rupees
8. Perimeter = 72cm
Length of each side = 72/4 = 18cm
9. Perimeter of a square = 4 x side = 4 x 24 = 96cm
10. Area of a rectangle = l x b = 7 x 6 = 42 sq. m
Cost of cementing = 42 x 50 = 2100 rupees
11. Length of each side = 60/3 = 20cm
12. Perimeter of a rectangle = 2 x (l + b)
= 2 x (40 + 25) = 2 x 65 = 130m
Total distance covered by him = 130 x 5 = 650 m
13. Area = 420 sq. m
Length = 20m
Width = 420/20 = 21m
14. Perimeter = 80cm
Length of each side = 80/5 = 16cm
15. Perimeter = 36m
Length of each side = 36/6 = 6m
