Let B be the centre of the circle $\displaystyle x^2+y^2-2 x+4 y+1=0$. Let the tangents at two points P and Q on the circle intersect at the point $\displaystyle \mathrm{A}(3,1)$. Then $\displaystyle 8 \cdot\left(\frac{\text { area } \triangle \mathrm{APQ}}{\text { area } \triangle \mathrm{BPQ}}\right)$ is equal to \_\_\_\_.
