Step-by-step explanation:
Area of rhombus= p*q/2
(where p is one diagonal and q is other)
p=45cm
q=30cm
Area of rhombus=45*30/2
=675cm²
Number of tiles in the floor=3000
Area of floor= Area of one tiles*Number of tiles
=675*3000
=2025000 cm²
=202.5m²
Cost of polishing the floor per m²= Rs4
Total cost of polishing the floor=4*202.5
=Rs 810
