Parameters
- graphics
- The graphics used to calculate areas and lengths.
- lengthUnit
- The length unit in which perimeters of polygons will be calculated. If unit is not specified, the units are derived from the spatial reference of the first geometry.
- areaUnit
- The area unit in which areas of polygons will be calculated. If unit is not specified, the units are derived from the spatial reference of the first geometry.
- calculationType
- The type of calculation to be preformed. e.g.(Planar,Geodesic,PreserveShape)
Return Value
Returns a collection of lengths and areas of each polygon that was passed into the function. The result length will be in the unit of measurement indicated by the "lengthUnit" parameter. The result area will be in the unit of measurement indicated by the "areaUnit" parameter.If no "lengthUnit" or "areaUnit" parameter is indicated then the result length and/or area will be expressed in the same units as the spatial referenceRequirements
