2a = 4√2
a = 2√2
h = a√3 = 2√2 × √3 = 2√6
2.
h = a√3 = 4/7
[tex]a = \frac{4}{7} \div \sqrt{3} = \frac{4}{7} \times \frac{1}{ \sqrt{3} } = \frac{4}{7 \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{4 \sqrt{3} }{7 \times 3} = \frac{4 \sqrt{3} }{21} [/tex]
[tex]obw = 3 \times \frac{4 \sqrt{3} }{21} = \frac{4 \sqrt{3} }{7} [/tex]
Proszę ;)
