Answer 2

Answer:

$\sf{\red{\underline{\underline{About\:the\:Figure\implies}}}}$ The above figure is a semi - circle with a diameter of 14cm.

$\huge{\underline{\underline{To\:find→}}}$

$\sf\purple{→Perimeter\:of\:the\:given\:figure}$

$\huge{\underline{\underline{Answer→}}}$

As the above figure is a semi-circle, so its perimeter=$\frac{1}{2}$ circumference of a circle +diameter.

$\dashrightarrow{r=\dfrac{d}{2}=\dfrac{14}{2}=7cm}$

$\sf\blue{→P=(\frac{1}{2}\times2πr)+d}$

$\sf\blue{→P=πr+d}$

$\sf\blue{→P=(\frac{22}{7}\times7)+14}$

$\sf\blue{→P=22+14}$

$\sf\blue{→P=36cm}$

$\sf{\boxed{\boxed{\pink{→P=36cm✔}}}}$

So Perimeter of the above semi-circle is 36cm which is the required answer.
