Question

diaganal of rhombus is 45cm 30cm. 3000 tiles required for flooring. find the cost of polishing the floor .cost is 4rs.permeter square.

Answer 1

area of rhombus=d₁d₂/2.
                             =45(30)/2
                             =1350/2
                             =675cm²
area of 1 tile=675cm²
area of 3000 tiles=675(3000)cm²
                               =20,25,000cm²
cost of 1cm²=4rs.
cost of 20,25,000cm²=4(20,25,000)rs.
                                     =81,00,000Rs.
