    Answer: length when perimeter is 78 units: a=26, b=13

    Length when perimeter is 156 units:

    a=26, b=52

    Step-by-step explanation: Given one side = 26, the other is twice as long

    Perimeter of a parallelogram = 2 (a+b)

    Using perimeter=78 = 2 (26+b)

    78=52+2b

    78-52=2b

    26=2b

    b=26/2

    b=13

    When perimeter is 78 units a=26, b=13

    Using perimeter = 156 units

    156=2 (26+b)

    156=52+2b

    156-52=2b

    104=2b

    b=104/2

    b=52
