Odpowiedź:
[tex]24 \sqrt{3} cm \div 3 = 8 \sqrt{3} cm[/tex]
a=8√3cn
[tex]h = \frac{a \sqrt{3} }{2} [/tex]
[tex]h = \frac{8 \sqrt{3} \times \sqrt{3} }{2} = \frac{8 \times 3}{2} = 4 \times 3 = 12[/tex]
h=12cm
P=[tex] \frac{ah}{2} [/tex]
P=[tex] \frac{8 \sqrt{3}cm \times 12cm }{2} = 4 \sqrt{3} cm \times 12cm = 48 \sqrt{3} \: {cm}^{2} [/tex]
