Question

Qual dessas está correta?

Answer 1

Resposta:

alternativa b

Explicação passo-a-passo:

AB => h² = a² + b² => h² = 4² + 4² =>  h² = 16 + 16 => $h = \sqrt{32} => h= \sqrt{16.2} => h = 4\sqrt{2} => AB = 4\sqrt{2}$

BC => h² = a² + b² => h² = 4² + 4² =>  h² = 16 + 16 => $h = \sqrt{32} => h= \sqrt{16.2} => h = 4\sqrt{2} => BC = 4\sqrt{2}$

CD => h² = a² + b² => h² = 6² + 4² =>  h² = 36 + 16 => $h = \sqrt{52} => h= \sqrt{13.4} => h = 2\sqrt{13} => CD = 2\sqrt{13}$

Logo:

AB + BC + CD => $=> 4\sqrt{2} + 4\sqrt{2} + 2\sqrt{13}=> 8\sqrt{2} + 2\sqrt{13}$
