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.
