Question

anonymous · Answer

Normally origami papers are square

so using the Pythagoras theorem

diagonal = sqrt(12^2 + 12^2) = sqrt(144 + 144) = sqrt(288) = 16.97 cm

anonymous · Answer

diagonal of a square is $$\sqrt{lenght of side ^{2} +lenght of side ^{2}} => \sqrt(144 + 144) =16.9705627 cm ^{2}$$
