you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.

You can't tell. There are an infinite number of triangles that all have a perimeter of 144.
to measure the perimeter we need a figure with boundaries and all the sides with dimensions
You simply just add up all of the sides
