The perimeter tool is broken. Individually, the lines add up to -750m. When put into a rectangle, it shows the perimeter as 390.

Hi Gordon, It sounds like you are using the perimeter measurement to obtain a distance. For a 2 sided area, this is twice the distance between them.
By Daft Logic on 30/09/2014
My measure is double the actual What have I done wrong
