Answer 1

Step-by-step explanation:

Area of marble Tiles => 12cm x 10cm

=> 120cm^2

=> 12m^2

Now let convert cm to m or vice versa. :)

Now let convert cm to m or vice versa. :)1 m =. 100cm

4m = 400cm

3m = 300cm

Area of wall => 400cm x 300cm

=> 120000cm^2

No of tiles required => 120000 x 120

=> 1000 Tiles

Costing as per ₹22.50 => 1000 x 22.50 => ₹22500
