area of square = 242 cm²
----
area of square = a²

where a is a side
----

242 = √a²

a= 15.55
--
length of wire = perimeter of square 

= 4(15.55)

=62.2 cm
------------------------
circumference of circle = 62.2 = lenght of wire

circumference of circle = 2πr

62.2 = 2 (3.14) r

62.2 = 6.28 r

r =9.9
--------------------------
area of circle = πr²

= 3.14 ( 9.9)²

3.14 x 98.01 

307.75
--------------
area of circle = 307.75 cm²
