Question
Find the perimeter of the given figure.

Answer

Radius of the given figure $= 6.3\ m$
Two sections in figure from a semi-circle.
Perimeter of semi-circular figure $=\frac{2\pi\text{r}}{2}+2\text{r}=\pi\text{r}+2\text{r}$
$=\frac{22}{7}\times6.3+2\times6.3$
$=22\times0.9+2\times6.3$
$=19.8+12.6=32.4\text{m}$
