A rectangular city park has a jogging loop that goes along a length width and diagonal of the park To the nearest yard find the length of the jogging loop if the length of the park is 125 yards?

This question could be answered if only it had also given either the width or the diagonal of the park.

Knowing only the length of the park, the jogging loop could still be anything at all.

Maybe there's some rule that relates the width of a rectangular city park to its length. We don't know it.
