Answer 1

$\begin{gathered}\green{\underline \bold{Given :}} \\ \tt: \implies Radius \: of \: circle = 7 \: cm \\ \\ \red{\underline \bold{To \: Find:}} \\ \tt: \implies Area \: of \: shaded \: region =?\end{gathered}$

$\huge { \mathcal{ \fcolorbox{red}{pink}{ \red{According\:to\:the\:Question}}}}$

$\begin{gathered}\tt \circ \: Side \: of \: square = 14 \: cm \\ \\ \bold{As \: we \: know \: that} \\ \tt: \implies Area \: of \: one \: shaded \: region = Area \: of \: square - 4 \times Area \: of \: quadrant \\ \\ \tt: \implies Area \: of \: one \: shaded \: region = {side}^{2} - 4 \times \frac{1}{4} \pi {r}^{2} \\ \\ \tt: \implies Area \: of \: one \: shaded \: region = {14}^{2} - \pi {7}^{2} \\ \\ \tt: \implies Area \: of \: one \: shaded \: region =196 - \frac{22}{7} \times 7 \times 7 \\ \\ \tt: \implies Area \: of \: one \: shaded \: region =196 - 22 \times 7 \\ \\ \tt: \implies Area \: of \: one \: shaded \: region =196 - 154 \\ \\ \green{\tt: \implies Area \: of \: one \: shaded \: region =42 { \: cm}^{2} } \\ \\ \tt \circ \: Total \: shaded \: part = 6 \\ \\ \bold{For \: Total \: shaded \: region : } \\ \tt: \implies Area \: of \:total\: shaded \: region =42 \times 6 \\ \\ \green{\tt: \implies Area \: of \:total \: shaded \: region =252 \: {cm}^{2} }\end{gathered}$
