Answer:
Area of 1 tile = 1/2 digonal1*diagonal 2
=1/2*45*30
=675cm sq.
Therefore area of 3000 tile is
3000* 675
=2,025,000
Cost of polishing floor is
2025000*225. (1m=100cml
=4,556,250,00

Given:
Diameter (d1) = 45 cm
Also,
Diameter (d2) = 30 cm
Number of tiles = 3000
Rate per m²= ₹2.250
Area of Rhombus
= 675 cm²
Area of 1 tile
= 675 cm²
Convert it into m²
As we know that :-
[1cm²= 1/10000m²]
Cost of Polishing the floor
= Total Area × rate
= ₹ 455.625
Therefore,
Total cost of polishing the floor
= ₹ 455.625
