Question

A swimming pool is 20m in length,15m in breadtg, 4m in depth find the cost of cementing its floor and wall at rupees 35 per m square

Answer 1

hello ☺..

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 

thank you ☺
