    Answer:

    Yes not possible but with dimensions

    Hers an example

    Step-by-step explanation:

    Since the tiles are in cm

    2

    , we have to convert the dimensions of the hall to cm first. It will be 1500 cm by 1200 cm. Hence the area of the floor is

    1500×1200=1800000cm

    2

    .

    Area of each tile is 30×20=600cm

    2

    . Hence the number of tiles required to cover the floor is:

    600

    1800000

    =3000.
