Odpowiedź:
1. a = [tex]\sqrt{6}[/tex], b = [tex]\sqrt{5}[/tex]
P = a × b = [tex]\sqrt{6}[/tex] × [tex]\sqrt{5}[/tex] = [tex]\sqrt{30}[/tex]
Obw = 2 × a + 2 × b = 2[tex]\sqrt{6}[/tex] + 2[tex]\sqrt{5}[/tex]
2. a = [tex]\sqrt{7}[/tex]
P = [tex]a^{2}[/tex] = [tex]\sqrt{7}^{2}[/tex] = 7
Obw = 4 × a = 4[tex]\sqrt{7}[/tex]
