    The new ribbon is 511.85 meter long.

    The total cost Rs. 6142.2

    Step-by-step explanation:

    First of all we convert all lengths to the standard unit that is meter.

    0.5 km = 500 meter

    1005 cm = 10.05 meter

    1800 mm = 1.8 meter

    total length in meters

    500+10.05+1.8 = 511.85

    total cost at the rate of Rs. 12 per meter will be

    511.85*12=6142.2
