Question

15. A floor is 45m long and 15m broad .It is covered with tiles each measuring
50cm by 30cm .Find the number of tiles required to cover the floor.

Answer 1

Answer:

Floor?

Length =40m=40*100=4000

Breadth==15*100=1500

Area =4000*1500=6000000

Tiles,

Length=60cm

Width=50

Area=50*60=3000cm

No of tiles required=6000000/3000=2000

Answer 2

Answer:

Given below are the dimensions of floor,

Length = 40 m.

Breadth = 15 m.

We know that,

Area = l∗b = 40∗15 = 600${m}^ {2}$

.

Here the length of one tile = 60 cm = 6/10 m.

Breadth of one tile = 50 cm = 5/10 m.

So the area of one tile = 6/10∗5/10

= 30/100

= 3/10${m}^{2}$

We know that,

Number of tiles = total area of floor / area of one tile,

Substituting the values,

=600/3/10

=(600∗10)/3

=2000.
