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.

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:

The area of the room = 42 m².

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

Side = 0.5 m.

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.

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