the area of rhombus is 280cm²
i.e 20*28*½
there are 2550 tiles
therefore total area is 714000
the cost is polishing 1m² is 25 then
we will convert the area in cm
therefore the area is 7140m²
there total cost of polishing is 7140x25=178500
therefore cost of polishing the floor is $178500

We have to divide the answer by 1000 becoz we have m^2
not by 1000 we have to divide by
100
