Odpowiedź:
a)
Pole = [tex]\sqrt{2}[/tex] * 3[tex]\sqrt{2}[/tex] = 3 * 2 = 6 cm kwadratowych
Obwód = [tex]\sqrt{2} * 2 + 3\sqrt{2} * 2 =[/tex] 2[tex]\sqrt{2} + 6\sqrt{2} = 8\sqrt{2}[/tex] cm
b)
Pole = [tex]\sqrt{3} * \sqrt{12} = \sqrt{12 * 3} = \sqrt{36} = 6[/tex] cm kwadratowych
Obwód = [tex]\sqrt{3} * 2 + \sqrt{12} * 2 = 2 \sqrt{3} + \sqrt{24} = 2 \sqrt{3} * 2 + 2\sqrt{3} = 6\sqrt{3}[/tex] cm
