Answer 2

$\Huge\mathfrak{answer \: !}$

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=400m²

=>So, the total area to be cemented =>1500m² +400m ²

=>1900m ²

=>Now, cost of cementing 1m ²

=Rs 27

Hence

Cost of cementing 1900m ²

=Rs 27×1900=Rs 51300
