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
