number of tiles=area of regular region

area of rectangular tile

area of rectangular tile=b

=12×5=60cm

Now,

The area of tile is given in cm whereas the area of region is given in m.

so,we have to convert them into same unit .

Area of rectangular region= b

=10×15

=150m

1m=100cm

150m= 150×100

=15000cm

number of tiles= area of regular region

area of tile

= 15000

60

=250 tiles are required.
