Answer:

heres your answer!

Step-by-step explanation

Side of the square =\sqrt{area}  =\sqrt{121}  =11 cm

Perimeter of the square = 4×side=44 cm

Therefore, length of the wire = 44 cm

We know,

Circumference of the circle = Length of the wire

Therefore, Circumference of the circle = 44 cm

Let the radius of the circle be r cm.

Then, 2πr=44

\frac{7}{22} ×r=44

r=7 cm

Therefore, area of the circle = πr²=  \frac{7}{22} ×49=154 cm²
