Parameters:

geometryGeometry or array_like

Geometry or geometries for which to compute the area.

**kwargs

See NumPy ufunc docs for other keyword arguments.

Examples

>>> from shapely import MultiPolygon, Polygon
>>> polygon = Polygon([(0, 0), (0, 10), (10, 10), (10, 0), (0, 0)])
>>> area(polygon)
100.0
>>> area(MultiPolygon([polygon, Polygon([(10, 10), (10, 20), (20, 20), (20, 10), (10, 10)])]))
200.0
>>> area(Polygon())
0.0
>>> area(None)
