Answer:
Measure of a marble tile=15 cm*20cm
Measure of the room=4 m*6m
Taking the measure of the room to be as 400 m*600 m
Area of one marble tile=l*b=15 cm*20 cm=300 cm^2
Area of the room=l*b=400 cm*600 cm=240000 cm^2
Therefore number of tiles=area of room/area of one tile
240000 cm^2/300 cm^2
=800 tiles_____Answer
