Answer:

80 tiles

Step-by-step explanation:

Convert m to cm:

  1. 1 m = 100 cm
  2. 4 m = 400 cm
  3. 3 m = 300 cm

Find the areas of the floor and 1 tile:

  1. Floor: 400 × 300 = 120,000 cm
  2. Tile: 75 × 20 = 1500 cm

Divide the areas to find the amount of tiles required to cover the floor:

  1. 120,000 ÷ 1500 = 80 tiles

I hope this helps!
