If the area of a triangle with vertices \( Z_{1}, Z_{2} \) and \( Z_{3} \) is
\( \mathrm{P} \)
the absolute value of the number \( \lambda i\left|\begin{array}{ccc}Z_{1} & \bar{Z}_{1} & 1 \\ Z_{2} & \bar{Z}_{2} & 1 \\ Z_{3} & \bar{Z}_{3} & 1\end{array}\right| \) then the value of \( 1 / \lambda \) is equal to
