Answer :

Given: d1 = 45 cm


d2 = 30 cm


To find: cost of polishing the floor.


Formula Used:


Area of rhombus = 1/2 × d1 × d2


Explanation:


For the given values,


Area of rhombus = 1/2 × 45 × 30


= 675 cm2


Area of one tile = 675 cm2


Area of 3000 tiles = 675× 3000 = 2025000 cm2


Area of tiles in m2 =


Cost of polishing 1 m2 = Rs 4


Cost of polishing 202.5 m2 = 202.5 × 4
