Side of a square is 15 cm. Area of square is 225 square units. Total area of 15 cm tiles=225*100=22500 square units. Now the size of the square is doubled. So, now the size of the square is 30cm. Now the replaced area is=900 square units. No. of 30 cm tiles required= 22500/900=25. So, 25 tiles are required to replace it.
