correct answer is 44cm​

Answer 1

Step-by-step explanation:

$area \: of \: wire \: (a) = 122 {cm}^{2} \\ let \: side \: be \: a \\ so \\ {a}^{2} = 122 \\ a = \sqrt{122} \\ \\ now \: \\ \\ circumference \: of \: circle(c) = perimeter \: of \: square \\ c = 4 \times a = 4 \times \sqrt{122 } = 4 \sqrt{122}$
