Answer 1

Answer:

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.
