Question

Hira Lal wants to cover the floor of a hall 5m wide and 6m long by square tiles. If each square tile is 20 cm, then find the number of tiles required to cover the floor of the hall.

Answer 1

Step-by-step explanation:

length length of hall = 6 and

breadth of hall = 5 cm

area = l×b

=6×5

=30m²

$area = 30. {m}^{2} = 300000 {cm}^{2}$

$side \: of \: tile = 20cm$

area=side×side

20×20=400cm²

so,no.of tiles required= area of hall/ area of tiles

$300000 \div 400 = 750$
