Dear guys,
If I have the x and Y coordinates for the centroids of a moving polygonal, and I want to find the distance travelled by this polygonal on a flat surface.
How I can calculate it using excel
please check the attached pic, this represents the path travelled by my polygonal, each point composed of the x and y coordinates for each centroid, numbers should be true, so I am looking for how to calculate the distance between each 2 points from these numbers on graph

please can you help me
