Explicación paso a paso:
[tex]Largo: L = \frac{3}{\sqrt{5} +1}[/tex]
[tex]Ancho: a = \frac{2}{\sqrt{5} }[/tex]
[tex]Perimetro: P = ?[/tex]
[tex]P= 2L + 2a[/tex]
[tex]P = 2 (\frac{3}{\sqrt{5}+1 } )+2(\frac{2}{\sqrt{5} } ) = \frac{6}{\sqrt{5} +1} +\frac{4}{\sqrt{5} } =\frac{6\sqrt{5}+4\sqrt{5}+4 }{\sqrt{25} +\sqrt{5} }[/tex]
[tex]P = \frac{10\sqrt{5}+4 }{5+\sqrt{5} }[/tex]
Racionalizando.
[tex]P = \frac{4+10\sqrt{5} }{5+\sqrt{5} } * \frac{5-\sqrt{5} }{5-\sqrt{5} } =\frac{20-4\sqrt{5} +50\sqrt{5}-10\sqrt{25} }{25-5} = \frac{46\sqrt{5}-30 }{20}[/tex]
[tex]Luego: P = \frac{23\sqrt{5} -15}{10}[/tex]
[tex]P = \frac{4+10\sqrt{5} }{5+\sqrt{5} }[/tex] Ó [tex]P = \frac{23\sqrt{5}-15 }{10}[/tex]
[tex]Area: A = ?[/tex]
[tex]A = L * a[/tex]
[tex]A = (\frac{3}{\sqrt{5} +1} )*(\frac{2}{\sqrt{5} } ) = \frac{6}{\sqrt{25}+\sqrt{5} }[/tex]
[tex]A = \frac{6}{5+\sqrt{5} }[/tex]
Racionalizando:
[tex]A = \frac{6}{5+\sqrt{5} } = \frac{6}{5+\sqrt{5} } * \frac{5-\sqrt{5} }{5-\sqrt{5} } =\frac{30-6\sqrt{5} }{25-5} = \frac{2(15-3\sqrt{5} )}{20}[/tex]
[tex]Luego: A = \frac{15-3\sqrt{5} }{10}[/tex]
[tex]A = \frac{6}{5+\sqrt{5} }[/tex] Ó [tex]A = \frac{15-3\sqrt{5} }{10}[/tex]
