$\Large{\blue{\tt{\underline{\underline{Given \ :-}}}}}$

${\sf{❥ \ Area \ of \ square \ = \ 81cm²}}$

$\Large{\green{\tt{\underline{\underline{To \ find \ :-}}}}}$

${\sf{✿ \ Circumference \ of \ circle}}$

$\Large{\orange{\tt{\underline{\underline{Solution \ :-}}}}}$

${\tt{The \ side \ of \ square \ will \ be \ equal \ to }}\\ {\tt{diameter \ of \ circle}}$

${\bf{\large{✯Area \ of \ square \ = \ Side ²}}}$

${\sf{↣ \ 81 \ = \ Side²}}$

${\sf{↣ \ Side \ = \ \sqrt{81}}}$

${\sf{↣ \ Side \ = \ 9cm}}$

________________________________________

Now,

Diameter of circle = 9cm

${\boxed{\sf \ ✯ \ Circumference \ of \ circle \ = \ \pi × diameter}}$

${\sf{\longmapsto \ Circumference \ = \ \frac{22}{7} × 9}}$

${\sf{\longmapsto \ Circumference \ = \ 28.28cm}}$
