Answer:

168 square tiles are required to cover the floor.

Step-by-step 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:

[tex]7\times 6[/tex]

[tex]=42\ m^2.[/tex]

The area of the room = 42 m².

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

Side = 0.5 m.

[tex]Area =(side)^2[/tex]

[tex]Area=(0.5)^2[/tex]

[tex]Area=0.25\ m^2.[/tex]

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.

[tex]=42\div 0.25[/tex]

[tex]=168.[/tex]

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