geoprocessing - How to calculate te area between contour lines on a DEM with QGIS 1.8?


Does anyone know how to calculate the area in km² for each altitudinal band (between 100 and 200, 200 and 300...) based on a DEM? I added the contour lines with a distance of 100 metres but could not find a way to modify them in order to allow area calculation. I am working with qgis 1.8.0. DEM is taken from ASTER.
