Question

each rectangular tile is 40 cm long and 30 cm wide. How many tiles will be required to cover the floor of a room with length=4.8m and breadth=2.4m.

Answer 1

the tiles are required to floor = 40+30= 70

Answer 2

Area of floor=l×b
= 4.8×2.4
=11.52
Area of a tile=0.4×0.3
=0.12
Hence tiles required to cover floor
=11.52/0.12
=96
