Odpowiedź:
a)
p =
[tex] \frac{10 \times 10}{2} = 50[/tex]
Obw =
[tex]10 + 10 + 10 \sqrt{2} = 20 + 10 \sqrt{2} [/tex]
b)
P=.
[tex] \frac{ \frac{12 \sqrt{2} }{2} \times \frac{12 \sqrt{2} }{2} }{2} = \frac{6 \sqrt{2 } \times6 \sqrt{2} }{2} = 36[/tex]
Obw=
[tex]2 \times \frac{12 \sqrt{2} }{2} + 12 = 12 \sqrt{2} + 12[/tex]
