Answer 2

Answer:

Hope my answer will help you.

Step-by-step explanation:

First we find the area of bathroom.

Area of bathroom = 3*3 = 9m² (convert m² into cm²)

9*100*100 = 90000cm²

Now we find area of one tile.

Area of tile = 15*15 = 225cm²

Required tiles = Area of bathroom/Area of one tile

= 90000cm²/225cm²

= 400 tiles
