Question

O lado de um quadrado mede \sqrt{2} cm .
Quanto mede sua diagonal?
Escolha uma:
a. \sqrt{6} cm
b. 2 \sqrt{2} cm
c. \sqrt{3} cm
d. 2 \sqrt{3} cm
e. 2 cm

Answer 1

$Resolu\c{c}\~ao \to \left\{\begin{array}{ccc}Diagonal(D) = l\sqrt{2}\\\\D = \sqrt{2}*\sqrt{2}\\\\D = \sqrt{2*2}\\\\D = \sqrt{2^2}\\\\D = \sqrt{4}\\\\\boxed{\boxed{Diagonal = 2\ cm}}\to Letra E\end{array}\right$
