For multi-geometries, it sums the perimeters of each component. It accepts `maxError` to control reprojection accuracy and `proj` to set the output units (defaulting to meters). The method returns a float value. The example demonstrates its use on a polygon, calculating and then displaying its perimeter, and displaying the polygon on a map.\n"]]
