Odpowiedź:
4. a)
[tex]h = \sqrt{3^{2} - 2^{2}} = \sqrt{9 - 4} = \sqrt{5} = 2,236[/tex]
P = a * h = 7 * 2,236 = 15,652
4. b)
[tex]h = \sqrt{4^{2} - 3^{2}} = \sqrt{16 - 9} = \sqrt{7} = 2,646[/tex]
P = a * h = 7 * 2,646 = 18,522
5. a)
[tex]b = \sqrt{10^{2} - 6^{2}} = \sqrt{100 - 36} = \sqrt{64} = 8[/tex]
P = a * b = 6 * 8 = 48
5. b)
[tex]a = \sqrt{2 * 5^{2}} = \sqrt{2 * 25} = 5\sqrt{2}[/tex]
[tex]P = a* h = 5\sqrt{2} * 5 = 25\sqrt{2}[/tex]
