The floor of a building consists of 5000 which are rhombus shaped and each of diagonals is 30cm and 20cm in length. Find the total cost of polishing the floor if the cost per m² is ₹ 3​

Answer 1

Answer:

1 floor of a building consist = 5000 rooms

each of diagnols of rhombus shaped rooms = 30m

and length = 20 m

area of each room = l x b = 20 x 30 = 600 m²

area of one floor = 600 x 5000 = 30,00,000m²

cost of polishing the floor per m² = Rs. 3

total cost of polishing the floor = 30,00,000 x 3 = Rs. 90,00,000
