Question

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

Answer 1

Length of floor=4.8 m
breadth of floor=2.4 m
Area of floor=l×b
= 4.8×2.4
=$11.52m^2$
length of tile=40 cm=0.4 m
bredth of tile=30cm=0.3 m
Area of a tile=0.4×0.3
$=0.12m^2$
Hence tiles required to cover floor
=$\frac{11.52}{0.12}$
=96
