as we have to cement floor and 4 walls
area to be cemented=area of floor×area of four walls
=20×14+2×3×14+2×3×20
=484m^2 =x
cost we need to pay= x ×15 RS=RS 7260

hiii!!!
here's ur answer...
given the Length of the swimming pool = 20m
breadth of the swimming pool = 14m
height ( depth ) of the swimming pool = 3m
ATQ,
we have to find the cost of cementing it's floor and walls.
so we will use CSA + 1 base formula.
CSA+1 base of the swimming pool = 2h(l+b) + lb
= 2 × 3 ( 20 + 14 ) + ( 20 × 14 )
= 6 × 34 + 280
= 204 + 280
= 484m²
total cost of cementing at the rate of ₹15 per m² = 484 × 15
= ₹7260
hope this helps..!!
