Answer 2

Answer:

972 tiles were required.

Step-by-step explanation:

1m= 100cm

So, 5.4m= 540cm

4.05m= 405cm

Area of the floor= 540cmx405cm (Used the formula of a rectangle which is, length x width)

= 218,700cm²

Area of the tiles = 15cmx15cm (Used formula of a square which is side x side)

= 225cm²

Tiles required = 218,700cm²/225cm²

= 972 tiles

Full Ans: 972 tiles are required to cover the rectangular floor.
