The edge length of a shape is the total length of all of the shape's edges. It can be considered to be the total extent of all of the shape's 1-subfacets in 1-dimensional space. The edge length of a polytelon is called its length. The edge length of a polygon is called its perimeter.
An edge length has dimensions of [length].
