For multi-geometries, it sums the perimeters of individual components. It takes `maxError` (tolerated reprojection error) and `proj` (output projection units) as optional arguments. The default `proj` is meters. The method, applied to a rectangle object, returns a float representing the calculated perimeter, which can be displayed with other parameters.\n"]]
