Question

A rectangular hall is 12m long and 6m broad.Its flooring is to be made of square tiles of side 30 cm.How many tiles will fit in the entire hall?

Answer 1

Answer:

800

Step-by-step explanation:

Floor area = 12×6 = 72 m^2

Tile area = (30/100)×(30/100) = 9/100 m^2

Tiles required = 72/(9/100) = 800

Answer 2

Answer:

Step-by-step explanation:

base is a rectangle so the area of base is l x b

=12x6

=72

One tile is 30cm = 30/100 m

No of tiles =72/30\100

=72 x 100/ 30

=24 x 10

=240 tiles are required
