    Answer:

    1 : 2

    Step-by-step explanation:

    First situation

    sides of triangle:-

    a=x, b=2x, c=3x

    then perimeter = a+b+c

    perimeter = x + 2x + 3x

    Perimeter = 6x

    Second situation(sides are doubled)

    sides of triangle:-

    a=2x, b=4x, c=6x

    then perimeter = a+b+c

    perimeter = 2x + 4x + 6x

    Perimeter = 12x

    Ratio of first situation to second

    Perimeter of first situation : Perimeter of second situation

    6x : 12x

    1 : 2
