Answer 1

heya!

here's ur answer frnd...

given the side of the room is 4.8m

area of the room=side×side(since it's a square room)

=4.8×4.8

=23.04m²

perimeter of the tile=1.2m

side×4=1.2m

side=1.2/4

side=0.3m

area of the tile=side×side

=0.3×0.3

=0.09m²

number of tiles to cover the room=23.04/0.09

=256

hence, 256 tiles are required to cover the floor.

total cost if each tile costs ₹27=256×27

=₹6912

hope this helps..!
