Question

17. A room measuring 7m by 6m is to be covered by square tiles of side 0.5m. Find

the number of tiles required to cover the floor.

Answer 1

168 square tiles are required to cover the floor.

Explanation:

Given:

A room measuring 7m by 6m is to be covered by square tiles of side 0.5m.

Now, to find the quantity of tiles required to cover the floor.

The room measures = 7m by 6m.

So, to get the area of the room:

`7* 6`

`=42\ m^2.`

The area of the room = 42 m².

Now, to get the area of square tiles by putting formula:

Side = 0.5 m.

`Area =(side)^2`

`Area=(0.5)^2`

`Area=0.25\ m^2.`

The area of the tiles = 0.25 m².

Now, to get the number of tiles required to cover the floor we divide the area of the room by the area of the tiles:

Area of the room ÷ area of the tiles.

`=42/ 0.25`

`=168.`

Therefore, 168 square tiles are required to cover the floor.
