Odpowiedź:
a)
P = [tex]\frac{14^{2}\sqrt{3} }{4}[/tex] = [tex]\frac{196\sqrt{3} }{4}[/tex] = [tex]49\sqrt{3}[/tex] dm
b)
[tex]h = \frac{a\sqrt{3} }{2} \\a = \frac{2h}{\sqrt{3} } = \frac{2*8\sqrt{3} }{\sqrt{3} } = 16\\P = \frac{a^{2} \sqrt{3} }{4} \\ \\P = \frac{256 \sqrt{3} }{4} \\\\P = 64\sqrt{3} cm[/tex]
