Assuming the tiles dimensions to be 25cm by 15cm.

Area of the entire Swimming pool= L x B = 15*25= 375m^2

Area of 1 tile is= 25*15= 375 cm^2.

375m^2= 375*100*100 cm^2

total number of tiles required is 3750000/375

= 10000 tiles

Answer 2

Answer:

10000

Step-by-step explanation:

area of pool = 25*15 m sq.

area covered by 1 tile = (25/100)*(15/100) m sq.

so

no. of tiles required= area of pool/ area covered. by 1 tile

=> no. of tiles= 100*100

= 10000
