I know this should be really simple, but it is not working out.(adsbygoogle = window.adsbygoogle || []).push({});

Say we have three vertices (0,0,0) (4,8,3) and (3,4,5)

I need to find the area of the triangle that it makes in three space with,

[tex]A\mbox{re}a\; =\; \frac{1}{2}\sqrt{\det \left( A^{t}A \right)}[/tex]

But it is not working out :(
