How we calculate the area between  contour lines?

Hi Satyendra,

One way could be using the contour lines to create polygons, but that will likely be very time consuming (if it even works).
For this you could use the Feature to Polygon tool which is available with ArcGIS for Desktop Advanced:

A better way would be to reclassify the DEM (assuming you have one to begin with) using a classification that corresponds to your contour lines:
http://resources.arcgis.com/en/help/main/10.2/index.html#/Reclassify/009z000000sr000000/

The resulting raster will be an integer raster. You can open the attribute table and multiply the number of pixels with the pixel size. This will give you the area for a class (area between two contour lines).

If you are looking for the area of each separated area try the Region Group tool:

Kind regards,
