Cost of polishing the floor = 0.5 rupees per cm^2

Area of 1 pllgm = b*h

= 3*5

= 15cm^2

Area of all the tiles = 15*2800

= 42000cm^2

The area of all the tiles is 42000cm^2.

Now we will find out the cost of polishing the floor

It is said that the cost of polishing the floor is 0.5 rupees per cm^2.

So, the cost of polishing the floor

= 42000*0.5

= ₹21000

Therefore, the cost of polishing the floor at ₹50 paise per cm^2 will be ₹21000.
