Length of the swimming pool = 20 m
Breadth of the swimming pool = 15 m
Depth of the swimming pool = 4 m
Area of four walls = 2h(l + b)
= 2 x 4(20 + 15)
= 8x(35)
= 280 m2.
Area of the base = length x breadth
= 20 x 15
= 300 m2.
Total area of cementing = 280 + 300 = 580 m2.
Cost of cementing = Rs 35 per sq m
Total cost of cementing = 580 x 35 = Rs.20,300
Step-by-step explanation:
Area of cementing floor and walls at the rate of 35m² is Rs. 20300 .
