    Answer: (2) 3 : 1
    Explanation:-
    The ratio of the areas of two squares =  9:1
    Formula-
    Area of a square = side x side

    The ratio of their side = sqrt.(9 : 1)
    = 3 : 1

    The ratio of their perimeters = 4 x 4 : 1 x 4
    = 12 : 4
    = 3 : 1
    Hence, the answer is (2) 3 : 1.
