Question

The floor of a building consists of 3000tiles which are rhombus shaped and each of its diagonals are 45 cm and 30 cm in length find the total cost of polishing the flour if the cost per m2 is4.​

Answer 1

Answer:

Rs. 810 is the cost of polishing

Step-by-step explanation:

diagonals of rhombus = 45 cm,30 cm

area of each rhombus = 1/2 x d1 x d2

= 1/2 x 45 x 30

= 45 x 15

= 675 cm^2

area of 3000 TILES = 3000 x 675

= 2025000cm^2

= 2025000/10000 m^2

= 202.5 m^2

cost of polishing the tiles per m^2 = Rs. 4

cost of polishing 202.5 m^2 = 4 x 202.5

Rs. 810
