geometryEngine planarArea Units

Dear,

I would like to calculate Area of geometry by geometry engine Planar Area function, but I have problem with units measurement.

My code is:

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

but i get an error in console:

Any idea to solved this problem please?

Best Regard.

Hi there,

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

Hope this helps,

I changed code into:

var area = geometryEngine.planarArea(geometry.geometry, "square-kilometers")

and message in console is in Attached file.

How to solved this problem?

Best regard.
