Answer 1

Answer: The number of tiles that required are 2000

Step-by-step explanation:

Given, A room has the dimensions 15 m x 12 m and marble tiles are 45 cm by 20 cm.

Then, the area of the floor = 15×12 m² = 180 m² = 1800000 cm²

and the area of the tile = 45×20 cm² = 900 cm²

∴Required tiles = 1800000/900 = 2000
