Question

A swimming pool is 40 m in length ,30 m in breadth and 2.2m.in depth.The cost of cementing its floor and the four sides at Rs 25/m2​

Answer 1

Step-by-step explanation:

hey mate,

Length of the swimming pool = 40 m

Breadth of the swimming pool = 30m

Depth of the swimming pool = 2.2m

Area of four walls = 2h(l + b)

= 2 x 2.2(40 + 30)

= 4.4x(70)

= 308m2.

Area of the base = length x breadth

= 40 x 30

= 1200 m2.

Total area of cementing = 308+ 1200 = 1508 m2.

Cost of cementing = Rs 25 per sq m

Total cost of cementing = 1508 x 25 = Rs. 37700

hope this would help you!!
