Answer 2

Answer:-

Area of square = 32 sq.cm

Option (3) is correct.

Step - by - step explanation:-

To find:-

→Area of square

Given:-

$\bf{radius \: of \: circle \: (r)= \frac{8 \sqrt{2} }{ \pi} }$

Solution:-

Length of wire (L)

$L \bf{= 2 \times \pi \times \frac{8 \sqrt{2} }{ \pi} } \\ \\L = \bf{ 16 \sqrt{2} }$

$\star \: \bf{side \: of \: square \: = \frac{16 \sqrt{2} }{4} = 4 \sqrt{2} }$

We know that-

$\bf{area \: of \: square \: = side \: \times side }\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bf{ = 4 \sqrt{2} \times 4 \sqrt{2} } \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bf{ = 32 \: sq. \: cm}$
