You can use the Calculate Geometry dialog box to update the area, length, or perimeter of shapefile features, since these properties are not automatically

Assuming that your data are being stored in a geodatabase the "Shape_Length", "Shape_Area", etc. fields are system fields that cannot be deleted and are maintained automatically by the geodatabase.

[>>>] ~[ ⇑] Studies Tradition Geographic features in a shapefile can be represented by points, lines, or polygons (areas). The workspace containing shapefiles may also contain dBASE tables, which can store additional attributes that can be joined to a shapefile's features. Below is an example of how shapefiles appear in ArcCatalog. Many geoprocessing tools, when operating on datasets, add one or two fields to the data: Shape_Length (for lines and polygons), and Shape_Area (for polygons). Geographic features in a shapefile can be represented by points, lines, or polygons (areas).

The F_AREA field created in the Output Feature Class will be populated with values for the area of each polygon feature in square units of the Output Coordinate System. There are alternative methods for creating an Area field for polygon features including: Calculate Field and the Geometry Calculator.

First, open up an ArcGIS session and load in the polygon data you want to calculate the area on. Make sure your data is in a projection system. Next, select the polygon file that you want to calculate area on and right click. This will open up a menu of options for that layer.

The F_AREA field created in the Output Feature Class will be populated with values for the area of each polygon feature in square units of the Output Coordinate System. There are alternative methods for creating an Area field for polygon features including: Calculate Field and the Geometry Calculator. By default, the Shape_Length field is automatically populated, as it is a system-generated and -managed field. Inaccurate conversions of the Shape_Length field can occur when attempting to change an existing coordinate system to one that uses a different unit of measurement. ~[ ⇑] features are defined in a GIS by the linear shape of the perimeter and some kind of reference point indicating that the space enclosed by those lines relates to a geographical feature. This reference point is referred to as a centroid, a seed or a label point.
