finding area in ListContourPlot

Hi-

I'm new to the site, and I've searched around a bit for the solution to this problem, but the answer doesn't seem too tractable. The nearest I've gotten was here: https://groups.google.com/forum/?fromgroups#!searchin/comp.soft-sys.math.mathematica/finding$20area$20of$20a$20contour$20region/comp.soft-sys.math.mathematica/Hs6KIWL3fvE/DnZQm6joE0gJ

I would like to find the area bounded by the 95% confidence level of an object like <plotname>=ListContourPlot[<listname>,Contours->chimin+9.2]. In the first place, I'm having trouble getting a list of the points that bound the contour region. I can use FullForm[<plotname>], followed by hunting through the (huge) FullForm output to do this, but I'd like to automate the process since I'll have to do this operation for dozens of contour plots.

Any help finding the area of region bounded in ListContourPlot or at least getting a list of points that define the region would be most appreciated.

Thanks very much,
Sam
