Answer 1

Answer:

=12

And The dimensions of a wall is 4.8m Not 48m

Step-by-step explanation:

=Length= 4.8 m

=Breath= 3.6m

=Area of the Wall = Length × Breath

= 4.8 × 3.6

= 17.28 m

= Size of square tiles = 1.2 m

= Area of one square of tiles = Size × Size

= 1.2 × 1.2

= 1.44 m

= Number of tiles = Area of the hall / Area of the one tiles

= 172.8 / 1.44

= 12m
