Answer 1

Answer:

150 tiles.

Step by step answer:-

Side of a tile = 20cm

Side of the square bathroom = 3m.

[As we know that 1m= 100cm]

So,3m=300cm.

Perimeter of a square= Side × 4

20×4

80cm.

Perimeter of a square= Side × 4

300×4

1200cm.

Total no.s of tiles to cover a square bathroom of side 3m=

Perimeter of the square bathroom ÷ Perimeter of the tile.

1200÷80

=150.

.°. No.s of tiles = 150.
