Question

14. The length and breadth of a playground are 70 m 30 cm and 42 m 70 %
cm. Find the cost of levelling it at the rate of * 2 per square metre.
Also, find the distance covered by a boy to take three rounds of the ground.​

Answer 1

Answer:

Cost = 6003.62

Distance= 678 m

Step-by-step explanation:

length = 70.3 m

breadth = 42.7 m

Area = (70.3* 42.7) m^2

= 3001.81 m^2

Total cost= 3001.81*2 = 6003.62

Perimeter = 2*(70.3+42.7)= 226 m

Distance covered by the boy = (226* 3)= 678 m
