Solution

As we know that

 \bf \pink{the \: formula \: of \: area \: of \: circle(a) = \pi {r}^{2} } \\   \bf \pink{a = \pi \:  {r}^{2} \: ................. \: 1st \: equation } \\ \\  \bf \purple{and} \\  \\  \bf \purple{circumference (c) = 2\pi \: r} \\  \\  \bf \blue{ =  > r =  \frac{c}{2\pi} ...........2nd \: equation} \\  \\  \bf \red{putting \: the \: value \: of \: r \: in \: equation} \\  \bf \red{1st \: from \: equation \: 2nd} \\  \\  \bf \pink{a = \pi \:  {r}^{2} } \\   \\   \bf \orange{a = \pi \:  \times ( \frac{c}{2\pi})^{2}  } \\  \\  \bf \green{as \: we \: know \: that \: } \\  \\  \bf \green{ \underline{according \: to \: question}} \\  \\  \bf \red{circumference \: (c) = 1m = 100cm} \\  \\  \bf \orange{ =  > a =  \cancel\pi \times  \frac{ {c}^{2} }{4 \times  \cancel \pi \times \pi} } \\  \\  \bf \orange{a =  { \frac{ { 7\times (100)}^{2} }{4 \times 22} } } \\  \\  \bf \orange{a =  \frac{\cancel100 \times 100 \times 7}{ \cancel4 \times 22}  } \\  \\  \bf \orange{a =  \frac{2500 \times 7}{22} } \\  \\  \bf \orange{a =  \frac{17500}{22} } \\  \\  \bf \orange{a = 795.45 \:  {cm}^{2}  \:  \: answer}
