Answer:160 tiles
Step-by-step explanation:
The room measures 5 m by 8 m, so we need to multiply them to find the total area of the floor to be covered
5 x 8 = 40 m squared
Now the square tile has a side of 0.5 m. All sides on a square are equal. We need to find the area of the square so:
0.5 x 0.5 = 0.25 m squared
Now to find the no. of tiles requires we just divide the floor's area by the tile's area
40 divided by 0.25 = 160
Therefore we need 160 tiles to cover the floor.
