#3**0 **

No need to separate I got it.

Area of a star(regular) of side length a

= \(\left(\dfrac{5\sqrt{10-2\sqrt5}}{8}+\dfrac{(3-\sqrt5)(\sqrt{10+2\sqrt5}+2\sqrt{5+2\sqrt{5}})}{8} \right)\cdot a^2\)

Checked. No mistakes. Just substitute and use a calculator :D

Although it is really complicated......

Anyone know what I am doing XD
