Percentage of area above x meters in a selection

I am trying to do the following: I would like to select a certain area of a map with elevation data, and then determine how many percent of the selected area are above a certain level of altitude. Like, how much of the selected area is above 2000m?
Is there a quick and easy way to do this with Global Mapper?
