fast answer 

If $\vec{r} \cdot \vec{a}=\vec{r} \cdot \vec{b}=\vec{r} \cdot
\vec{c}=\frac{1}{2}$ for some non-zero vector $\vec{r}$, then
the area of the triangle whose vertices are $A(\vec{a}),
B(\vec{b})$ and $C(\vec{c})$ is $(\vec{a}, \vec{b}, \vec{c}$
are non coplaner)
A) $\\vec{a} \vec{b} \vec{c}\|$
B) $1\vec{r}|$
C) ||$\vec{a} \vec{b} \vec{c} |\vec{r}|$
D) $\frac{\mid[\vec{a} \vec{b} \vec{c} |\vec{r}|}{5}$|
