how do i calculate polygon area with arcobjects?

Question

i'd like to develope an application with arcengine that can calculate area of a polygon .

i wrote the below code to select a polygon in combobox

 for (int i = 0; i < pmapcontrol2.LayerCount; i++)
                    {

                        Pfeaturelayer = (IFeatureLayer)pmapcontrol2.get_Layer(i);
                        if (Pfeaturelayer.FeatureClass.ShapeType == esriGeometryType.esriGeometryPolygon)
                        {


                            cmbfeaturelayer.Items.Add(pmapcontrol2.get_Layer(i).Name);
                        }
                    }

but i couldn't wrote code to calculate pfeaturelayer area . i think i should use Ilayer interface and Ilayer use Ifeature to calculate area not ifeaturelayer . is there any way to use Ifeature for this application ? thank you.

Here is a link for some sample code that calculates area of selected polygon feature.
