    Answer: (4) none of these 

    Solution:-
    Let the diagonal of a square be D and another square be 2 D

    Then, ratio of their areas = {(2 x D)^2/2}/{(2 x 2 D)^2/2}
     =  D^2/4 D^2

     = 1/4 

    Then, the ratio of  their area will be 1: 4.

    Hence, the correct answer is option (4) none of these.
