var area=geometryEngine.planarArea(geometry.geometry, units.SQUARE_KILOMETERS)

but i get an error in console:

Any idea to solved this problem please?

Hi there,

Looks like you need to pass in  "square-kilometers" as documented in the SDK doc:

3.x: https://developers.arcgis.com/javascript/3/jsapi/esri.geometry.geometryengine-amd.html#planararea

4.x: https://developers.arcgis.com/javascript/latest/api-reference/esri-geometry-geometryEngine.html#ArealUnits

Hope this helps,
