Answer 1

Step-by-step explanation:

get the area of the floor of the room first:

4.8 × 4.8 =23.04m square.

then get the area of one tile which will be the perimeter of the tile divided by 4 to get 0.3

the the 0.3 × 0.3 =0.09m squared.

to get the number of tiles take the area of the room and divide by the area of one tile

=23.04/0.09= 256 tiles

one tile costs 27 what about 256

=256× 27 = 6912

it will cost 6912.
