 From a point $P$ on the parabola $x^{2}=4y$, draw a perpendicular line to the directrix of the parabola, and let the foot of the perpendicular be $M$, with $|PM|=5$. Let the focus of the parabola be $F$. Then

The area of $\triangle MPF$ is $\boxed{\text{\_\_\_\_\_\_\_\_}}$. Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
