Question

A swimming pool is 15m in lenght 12 m in breadth and 2m in depth find the cost of cementing the floor and walls at the rate of 15 per sq m

Answer 1

Area of 4 walls of the swimming pool

= 2h (l + b)
= 2*4 (20 + 15)
= 8 * 35
= 280 m2

Area of the floor of the swimming pool

= l * b
= 20 * 15
= 300 m2

TOTAL AREA

= 280+300
= 580 m2

Cost of cementing the swimming pool @ Rs. 12/m

= 580 * 12
= Rs. 6960
