Odpowiedź:
[tex]h = \frac{a \sqrt{3} }{2} [/tex]
[tex]6 \sqrt{3} = \frac{a \sqrt{3} }{2} ....... \times 2 \\ 12 \sqrt{3} = a \sqrt{3} ..... \div \sqrt{3} \\ 12 = a[/tex]
[tex]p = \frac{ {a}^{2} \sqrt{3} }{4} [/tex]
[tex]p = \frac{ {12}^{2} \sqrt{3} }{4} = \frac{144 \sqrt{3} }{4} = 36 \sqrt{3} [/tex]
prawda
[tex]obw = 12 \times 3 = 36[/tex]
falsz
