Correct option is

3000

Length of swimming pool l=30m

Breadth of swimming pool b=20m

Height of swimming pool h=1.5m

The total surface area of pool= Lateral surface area + Area of base

=2h(l+b)+(l×b)

=2×1.5(30+20)+(30×20)

=750m

Side of square tile a=50cm=0.5m

Area of 1 tile =a×a=0.5×0.5=0.25m

Number of tiles =

area of tile

area of pool

0.25

750

Number of tiles =3000

Therefore 3000 tiles are required.
