@MrNood hey thanks for replying!
For each side you can create a right angle triangle - its vertical height is the difference in y values, and the horizontal length is the difference in x values. You can then use Pythagoras to find the 'hypotenuse' (which is the length of 1 side). Do that for all 4 sides and add to get the perimeter: |dw:1406218906690:dw|
