m.​

Answer 1

Answer:

7500 pieces of 4x2.5cm tiles

Step-by-step explanation:

Let's convert the tile to metre:

4cm = 0.04m

2.5cm = 0.025m

0.04 x 0.025 = 0.001m² (area of tile)

For area of room,

5/2m = 2.5m

3m x 2.5m = 7.5m² (area of room)

To get the number of tiles, divide the room area by the tile area:

7.5m ÷ 0.001m = 7,500 tiles pcs
