A wire can be bent in the form of a circle of radius 56 cm. If it is bent in the form of a square, then its area will be :

Answer: Option C

Length of wire :
$$\begin{array}{rl}& =2\pi \times R\\ & =\left(2\times \frac{22}{7}\times 56\right)cm\\ & =352cm\end{array}$$
Side of the square :
$$\begin{array}{rl}& =\frac{352}{4}cm\\ & =88cm\end{array}$$
Area of the square :
$$\begin{array}{rl}& =\left(88\times 88\right)c{m}^2\\ & =7744c{m}^2\end{array}$$
