P1 = 8 * 8 / 2 = 32
8 / 2 = 4
4^2 + h^2 = 4[tex](\sqrt{10})^{2}[/tex] | - 4^2
h^2 = 4[tex]\sqrt{10}^{2}[/tex]- 4^2
h^2 = 16 * 10 - 16
h^2 = 144 | [tex]\sqrt{}[/tex]
h = 12
P2 = 8 * 12 / 2 = 48
P = 32 + 48 = 80
Obwód = [tex]4\sqrt{10} + 4\sqrt{10} + 8\sqrt{2} + 8 = 8\sqrt{10} + 8\sqrt{2} + 8[/tex]
Pozdrawiam :D.
