Side of the tile(square) = 9 cm

Area of the tile = 9×9=81cm^2

Side of the floor of the bathroom(Square) = 720 cm

Area of the floor = 72×72=5184cm^2

No of tiles needed to fit in the floor = 
Area of the floor/Area of the tile =5184/81= 64

cost of tiling = Rs 7.5 per tile

Total cost = 7.5×64 = Rs480
