Question

The dimensions of room are 15 m and 10 m. Half of the room is to be covered with blue tiles and half with white tiles. The length of blue and white tiles are 15 cm and 20 cm respectively, and breadth of blue and white tiles is 10 cm and 15 cm respectively. Find the no of tiles of each color required to cover the room

Answer 1

Area of the floor=l x b

= 15x10

=150m^2

Area of blue tiles=15x10

=150cm^2

=150/10000=0.015m^2

Area of white tiles=20x15

=300cm^2

=300/10000m^2=0.03m^2

No. of blue colour tiles=75/0.015

=75000/15=5000 tiles

No. of white colour tiles=75/0.03

=7500/3=2500.
