The floor of a building consists of 2000 tiles which are rhombus shaped and each of its

diagonals are 45cm and 30cm. Find the cost of polishing the floor at Rs 5 per m2

.

Answer 2

Answer:

We know that,

Area of rhombus = 1/2 × d1 × d2

Area of rhombus = 1/2 × 45 × 30

Area of rhombus = 1350/2 = 675

So, Area of rhombus = 675 cm^2

∴ Area of one tile = 675 cm^2

Now, Area of 3000 tiles = 675× 3000 = 2025000 cm^2

Area of tiles in m^2 = 2025000/10000 = 202.5 m^2

Total cost for polishing the floor = 202.5× 4 = Rs 810

1012.5 is the cost for polishing the floor if polishing the floor at Rs 5 per m^2
