Answer 1

Hey mate here is your answer

Answer:

3000 tiles

Step-by-step explanation:

the rectangular swimming pool:

length= 30m

breadth=20m

height=1.5m

the total surface area of pool= lateral surface area + area of base {l x b}

2h[l+b] +l x b

2 x 1.5 [30+20] + 30 x 20 = 750 m sq

SQUARE TILE 

side of square=50cm=0.5m

area of 1 square tile = a x a = 0.5 x 0.5 = 0.25m sq 

no of tiles = area of pool / area of one tile.

no of tiles = 750/0.25 = 3000

therefore 3000 tiles are required.

Hope it helped you :)
