For multi-geometries, it sums the perimeters of each component. The function `perimeter()` takes an optional `maxError` to control reprojection accuracy and a `proj` argument to specify the output's units (defaulting to meters). It returns a floating-point number representing the perimeter length. The `feature` is the target for calculation.\n"]]
