    Answer: (4) 616 cm^2

    Explanation:-
    The perimeter of the circle = 88 cm

    Formula-
    The perimeter of the circle = 2 x pai x r

    Then, 2 x 22 x r/7 = 88
    r = 2 x 7
    r = 14 cm

    Formula-
    The area of the circle = pai x r^2

    Then, the area of the circle = 22 x 14 x 14 /7
    = 22 x 28
    = 616 cm^2

    Then, the area of the same circle is 616 cm^2.

    Hence, the answer is (4) 616 cm^2.
