Are of a square = \(\frac{diagonal^2}{2}\).

Given: \(\frac{diagonal^2}{2}=x\);

\(diagonal=\sqrt{2x}\).

Answer: B.

Hello

Bunuel isnt the formula of the area of square \(a^2\) where \(a\) is side of square ?

is it another formula ? \(\frac{diagonal^2}{2}\). does diagonal of square mean \(a\sqrt{2}\)

cause you write so \(diagonal^2\)

have a great monday
