Odpowiedź:
Pc = Pp + Pb = [tex]a^{2}[/tex] + 4 * [tex]\frac{1}{2}[/tex] ah =
Pc = [tex]6^{2}[/tex] + 2 * 6 * h
Pc = 36 + 12 * 6 [tex]\sqrt{3}[/tex]
Pc = 36 + 72 [tex]\sqrt{3}[/tex]
musimy obliczyc H = x

[tex]x^{2} + b^{2} = c^{2}[/tex]
[tex]x^{2} + 6^{2} = 12^{2}[/tex]
[tex]x^{2}[/tex] = 144 - 36
[tex]x^{2}[/tex] = 108
x = [tex]\sqrt{108[/tex]
x = 6[tex]\sqrt{3}[/tex]
