Perimeter of square =4*11=44cm

44= circumference of circle

44=2πr
44*7/22 =2r
2*7/2 =r
7=radius
Area =πr²
Area =22*7*7/7
Area =22*7=154

abhi569: Is it correct?
abhi569: Ur welcome

side of square= 11cm

perimeter of square = 11 × 4 cm
= 44cm

given,

circumference= perimeter of the square

circumference \:  = 2\pi \: r
let the radius of the circle be r

44 = 2 \times  \frac{22}{7}  \times r

 \frac{44 \times 7}{2 \times 22}  = r
radius = 7cm

area \: of circle \:  = \pi {r}^{2}

 =  \frac{22}{7}  \times 7 \times 7

area of the circle= 154 cm²
