Question

the floor of a building consists are 3000 tiles which are the Rhombus shaped and each of a diagonal are 45 cm and 30 cm in length find the total cost of polishing the floor if the cost per m in RS4

Answer 1

Step-by-step explanation:

Area of rhombus= p*q/2

(where p is one diagonal and q is other)

p=45cm

q=30cm

Area of rhombus=45*30/2

=675cm²

Number of tiles in the floor=3000

Area of floor= Area of one tiles*Number of tiles

=675*3000

=2025000 cm²

=202.5m²

Cost of polishing the floor per m²= Rs4

Total cost of polishing the floor=4*202.5

=Rs 810
