a)
[tex]a = 1 \\ 2a = 2 \\ a \sqrt{3} = \sqrt{3} [/tex]
Zatem pole
[tex]a \times a \sqrt{3} = 1 \times \sqrt{3} = \sqrt{3} [/tex]
Obwód
[tex]1 + 2 + \sqrt{3} = 3 + \sqrt{3} [/tex]
b)
[tex]a = 2 \\ 2a = 4 \\ a \sqrt{3} = 2 \sqrt{3} [/tex]
Zatem pole
[tex]a \times a \sqrt{3} = 2 \times 2 \sqrt{3} = 4 \sqrt{3} [/tex]
Obwód
[tex]2 + 4 + 2 \sqrt{3} = 6 + 2 \sqrt{3} [/tex]
