Question

A floor is 40 m long and 15 m broad . It is covered with tiles , each measuring 60 cm by 50 cm . Find the number of tiles required to cover the floor.

Answer 1

Here is your solution

GIVEN:-

A floor is 40 m long and 15 m broad .

Covered with tiles , each measuring 60 cm by 50 cm.

Now

Area of floor= Lenght ×breadth =40×15=600m^2

Area of tiles =60×50=3000cm^2=30m^2

Now

Number of tiles required => area of floor/Area of 1 tiles

=>600m^2/30m^2=20

hence

Number of tiles required to cover the floor is 20

hope it helps you

Answer 2

Answer:

Step-by-step explanation:

Given:

A floor is 40m by 15m

each tile is 60cm by 50 cm

Area of the floor = LxB = 40mx15m = 600 m²

Area of the tile = 60cm x 50cm = 3000cm²= 0.3 m²

Number of tiles required = Area of the floor / Area of a tile

= 600/0.3= 2000 tiles

2000 tiles are required
