Utilize the provided measurements in the following diagram to solve the following problem.

A telescope is positioned on top of a mountain with its lens located at point P. Pa represents the distance from the lens to the photographic plate ab, while uv represents the length of a river flowing through a straight path in the valley. Determine the length of the river.
