~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

\mapsto  \mathtt{We\ have}

\mapsto  \mathtt{Radius\ of\ circle}  \mathrm{=\ 14cm.}

\mapsto  \mathtt{Length\ of\ arc}  \mathrm{=\ 22cm.}

\mapsto  \mathtt{Using\ formula,}

\mapsto  \mathtt{Angle}= \dfrac{radius}{arc}

\mapsto  \mathtt{Now,}

\mapsto  \mathtt{Angle}= \dfrac{22}{14}

\mapsto  \mathtt{Angle}= \dfrac{22}{2 × 7}

\mapsto  \mathtt{Angle}= \dfrac{\pi}{2} \because {\pi}= \dfrac{22}{7}

\mapsto  \mathtt{Angle}= θ = \dfrac{\pi}{2}

\mapsto  \mathtt{So,}

\mapsto  \mathtt{Area\ of\ sector}= \dfrac{θ}{360°} × {\pi}r²

\mapsto \dfrac{90°}{360°} \dfrac{22}{7} × 14 × 14

\mapsto \dfrac{1}{4} × 22 × 2 × 14

\mapsto 22 × 7

\mapsto = 154sq.cm.
