Question

Jatin wants to cover the floor of a room 3 metre wide and 4 m long by square tiles if each sq tile is of side 0.5 m then find the number of tiles required to cover the floor of the room

Answer 1

Lengthof the floor = 4m and breadth (wide) of the floor = 3m

Area of the floor = l × b
= 4 × 3
= 12m²

Length of the side of the square tile is 0.5m.

Area of the square tile = side²
= 0.5 × 0.5
= 0.25m²

No. Of square tiles required to cover the floor = 12/0.25
= 48

Hence, 48 tiles are required.

Answer 2

Given:

The floor of a room is 3 m wide and 4 m long. The Jatin want to cover the floor with square tiles. Each square tile has a side of 0.5 m.

To find:

The number of tiles required to cover the floor of the room.

Solution:

As given,

we have,

The width of the floor = 3 m

The length of the floor = 4 m

So,

The area of the floor

$= length \: \times width$

$= 4 \times 3$

$= 12 \: {m}^{2}$

Now,

The side of a square tile = 0.5 m

So,

the area of one square tile

$= {(side)}^{2}$

$= {(0.5)}^{2}$

$= 0.25 \: {m}^{2}$

So,

the number of tiles required to cover the floor

$= \frac{area \: of \: the \: floor \: }{area \: of \: one \: tile}$

$= \frac{12}{0.25}$

$= \frac{12 \times 100}{25}$

$= 12 \times 4$

$= 48$

Hence, the number of tiles required to cover the floor of the room is 48.
