Answer 2

Answer:

51.66 Rs.

Step-by-step explanation:

A swimming pool is 20m in length ,15m in breath and 4m in depth.

Area of One wall of swimming pool = Lenght × depth = 20 × 4 = 80

There are four walls = 80 × 4 = 320 m

Area of floor of swimming pool = Lenght × breath = 20 × 15 = 300 m

Total area for cementing = 320 + 300 = 620 m

Total cost = 620/12 = 51.66 Rs.
