What does finding the area and perimeter get us?

Re: please find the area and perimeter
Circle segment area:

$r\text{:=}1;$
$\theta \text{:=}30*\frac{\pi }{180};$
$\text{segmentHyG}\text{:=}\frac{1}{2}r^2(\theta -\text{Sin}[\theta ])$ = $\frac{1}{2} \left(-\frac{1}{2}+\frac{\pi }{6}\right)$

Central square area:

$(2\text{Sin}[15{}^{\circ}])^2$ = $\frac{1}{2} \left(-1+\sqrt{3}\right)^2$

$S\text{:=}4\text{segmentHyG}+(2\text{Sin}[15{}^{\circ}])^2$ = $\frac{1}{3} \left(3-3 \sqrt{3}+\pi \right)$

Perimeter:

Perimeter= 4 $\text{arcHyG}\text{:=}r \theta$ = $\frac{2 \pi }{3}$
