L=12m=12×100cm=1200cm. (1m=100cm)
b=6m=6×100cm=600cm
area of room=l×b
1200×600=720000cm²
a=30cm
area of square tile=a×a
30×30=900cm²
tiles required=area of room/area of tiles
720000/900=800tiles required
in case of 15 cm tiles
a=15cm
area of tile=15×15=225cm²
required tiles=area of room/area of tile
720000/225=3200tiles required
