Answer 1

Answer:

Step-by-step explanation:

Given

Length of swimming pool =50m

Breadth of swimming pool =30m

Depth (Height) of swimming pool =2.5m

Now

Area of floor =50×30=1500m

2

Area of four walls =2(50+30)×2.5=160×2.5=400m

2

So, the total area to be cemented =1500m

2

+400m

2

=1900m

2

Now, cost of cementing 1m

2

=Rs 27

Hence

Cost of cementing 1900m

2

=Rs 27×1900=Rs 51300
