Multi-geometry lengths are the sum of their components' lengths. It accepts optional `maxError` and `proj` arguments to define error tolerance and projection units, respectively. The default unit is meters. Examples demonstrate applying `length()` to a BBox in both JavaScript and Python, showcasing how to print and display the resulting length alongside the geometry.\n"]]
