Find the length of sides of a polygon

Question

Hi All Greetings

How can I find the length of sides of a polygon ( Not Perimeter of the polygon).  Is the following right approach or is there any simpler approach please ?

1. find the number of rings in the polygon

2. loop through them

3. calculate length from the start point to end point

Thank you

Thank you again, Still did not work . I used the traditional way to find out the length of a line √((x_2-x_1)²+(y_2-y_1)²)‍

That tells me that you have to run the geometry through the simplify method first then.

Thanks. This is what I think I am doing. But keep getting error : "The operation cannot be performed on a non-simple geometry." function graphicDimension(resultGraphic) { require(["esri/geometry/Polyline", "esri/tasks/support/LengthsParameters", "esri/tasks/GeometryService", "esri/geometry/Point"], function (Polyline, LengthsParameters, GeometryService, Point) { for (i = 0; i < resultGraphic.geometry.rings.length; i++) { // value 1 polygon for (j = 0; j < resultGraphic.geometry.rings[i].length; j++) { //value 6 points fromPoint = new Point (resultGraphic.geometry.rings[i][j]); toPoint = new Point( resultGraphic.geometry.rings[i][j + 1]); //console.log(fromPoint, toPoint); paths = [ [fromPoint.x, fromPoint.y], [toPoint.x, toPoint.y] ] polyLine = new Polyline({ paths: [paths], spatialReference: app.view.spatialReference }); lengthParams = new LengthsParameters(); lengthParams.calculationType = "geodesic"; lengthParams.geodesic = true; lengthParams.polylines = [polyLine]; lengthParams.lengthUnit = "METER"; geomSerVice = new GeometryService(geometryServiceUrl); geomSerVice.lengths(lengthParams, function (result) { console.log(result.lengths[0]); alert("length"); }); // debugger; } } }); };‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
