__________Heyy Buddy ❤_________

______Here's your Answer _________

Area of Pool = Area of 4 side of pool + Area of base.

Now,

Area of base = l × b

=> 30 × 20

=> 600 m^2.

Now,

Area of 4 wall of pool = 2( l + b) × h

=> 2 ( 30 + 20) × 1.5

=> 2 × 50 × 1.5

=> 2 × 5 × 15

=> 150 m^2

Now, Area of pool = 600 + 150

=> 750 m^2.

Area of 1 tile = 50 m^2.

Then, Number of tiles = 750 / 50

=> 15 tiles.
