Question

Alisha wants to cover the floor of a room 8 m long and 5 m wide with rectangular tiles. If each rectangular tile is of length 40 cm and 10 cm find the number of tiles required to cover the floor of the room.

Answer 1

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.
