I need your guidance on the problem below. I am using qgis.I am new to GIS and also qgis tool. Hence please excuse me if the terminologies were not appropriately used.

There are two layers imported into the qgis project.Layer-1 (green) has attributes ID, area, codeLayer-2 (brown) has attributes station, shp_area, name.

I want to divide the polygons by overlapping and then add a new field value with the divided polygon's respective area. Other fields will remain the same of Layer-1For e.g. Along the border of one polygon (brown border), a larger polygon (green) was divided into two polygons. The total area before division was 125sqm. After division (shown in red), the areas respectively became 70sqm and 55sqm.

I want to do this in the entire shape file and store the new output (divided green areas) as Red-layer.

Any guidance will be very helpful. Once this is resolved, I will post back the reply with solutions that worked for me. Advance thank you all for your guidance.Best wishesMN
