Korzystam z Tw. Pitagorasa aby obliczyć x oraz y.
[tex]Obliczam~~x:\\\\x^{2} =1^{2} +1^{2} \\\\x^{2} =1+1\\\\x^{2} =2~~\land~~x > 0~~\Rightarrow~~x=\sqrt{2} \\\\obliczam~~y:\\\\y^{2} =(\sqrt{2} )^{2} +1^{2}\\\\y^{2} =2+1\\\\y^{2} =3~~\land ~~y > 0~~\Rightarrow~~y=\sqrt{3} \\\\P_{1} =\dfrac{1}{2} \cdot 1\cdot 1\\\\P_{1} =\dfrac{1}{2}\\\\P_{2} =\dfrac{1}{2}\cdot 1\cdot \sqrt{2} \\\\P_{2} =\dfrac{\sqrt{2} }{2} \\\\P_{p} =1\cdot 1\\\\P_{p} =1\\\\P_{c} =2\cdot P_{1} +2\cdot P_{2} +P_{p} \\\\[/tex]
[tex]P_{c} =2\cdot \dfrac{1}{2} +2\cdot \dfrac{\sqrt{2} }{2} + 1 \\\\P_{c} =1+\sqrt{2} +1\\\\P_{c} =2+\sqrt{2}[/tex]
