Consider the lines $\displaystyle \mathrm{L}_1: x-1=y-2=\mathrm{z}$ and $\displaystyle \mathrm{L}_2: x-2=y=\mathrm{z}-1$. Let the feet of the perpendiculars from the point $\displaystyle \mathrm{P}(5,1,-3)$ on the lines $\displaystyle \mathrm{L}_1$ and $\displaystyle \mathrm{L}_2$ be Q and R respectively. If the area of the triangle $\displaystyle P Q R$ is $\displaystyle A$, then $\displaystyle 4 A^2$ is equal to :
