Answer:
ANSWER
Side of the square =
area
=
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
2×
7
22
×r=44
r=7 cm
Therefore, area of the circle = πr
2
×49=154 cm
