3. Find the perimeter of an equilateral triangle of side 7 cm?
4. Find the area of a square of side 10cm?
5. Two sides of a triangle are 5 cm and 7cm. The perimeter of a triangle is 20 cm. Find the length of third side?
6. The perimeter of a square is 80m. Find the length of each side?
7. The perimeter of an equilateral triangle is 60 cm. Find the length of each side?
8. Find the perimeter of a regular pentagon with each side measuring 5 cm?
9. Find the perimeter of a rectangle of length 7.5cm and 3 cm?
10. The area of a rectangular garden 9m long is 54 sq. m. find the width of the garden?
11. Find the cost of fencing a rectangular park of length 80m and width 60m at the rate of 8 rupees per meter?
12. Find the area of a square field of side 25m?
13. The area of a square is 144 sq. cm. Find the length of each side?
14. Find the perimeter of a regular hexagon with each side measuring 10m?
15. The perimeter of a regular pentagon is 125cm. How long is its each side?

1. Area of the rectangle = length x breadth = 11 x 5 = 55 sq. cm
2. Perimeter = 8 + 10 + 12 = 30 cm
3. Perimeter of an equilateral triangle = 3 x side = 3 x 7 = 21 cm
4. Area of a square = side x side = 10 x 10 = 100 sq. cm
5. Length of third side = 20 – (5 + 7) = 20 – 12 = 8 cm
6. Length of a side = 80/4 = 20m
7. Length of each side = 60/3 = 20 cm
8. Perimeter of regular pentagon = 5 x side = 5 x 5 = 25 sq. cm
9. Perimeter = 2 x (l + b) = 2 x (7.5 + 3)= 2 x 10.5 = 21 cm
10. Given length = 9m, Area = 54 sq. m
Width = Area/length = 54/9 = 6m
11. Given length = 80m, breadth = 60m
Perimeter = 2 x (l + b) = 2 x (80 + 60) = 2 x 140 = 280m
Cost of fencing = 280 x 8 = 2240 rupees
12. Area of a square = side x side = 25 x 25 = 625 sq. m
13. Area = 144 sq. cm
Length of each side = Square root of 144 = 12 cm
14. Perimeter of a regular hexagon = 6 x side = 6 x 10 = 60m
15. Length of each side = 125/25 = 5cm
