a)
[tex]2a = 8cm \\ a = 4cm \\ a \sqrt{3} = 4 \sqrt{3} cm[/tex]
Obwód
[tex]8cm + 4cm + 4 \sqrt{3} cm = (12 + 4 \sqrt{3} )cm[/tex]
b)
[tex]a \sqrt{2} = 6cm \\ a = \frac{6}{ \sqrt{2} } = \frac{6 \sqrt{2} }{2} = 3 \sqrt{2} cm[/tex]
Obwód
[tex]6cm + 3 \sqrt{2}cm + 3 \sqrt{2} cm =( 6 + 6 \sqrt{2} )cm[/tex]
