I do not care if you don't think it will really happen; you don't believe it don't bother answering.

The easiest way to answer this is to look at a topographic map of the area in question. Then, anything below the 20 foot contour line would be ocean.
In some areas, it would be within a few hundred feet of the ocean but in many others, it could be several miles before you get above 20 feet.
There is a website that will crudely show you the coastlines of the world with you choosing the depth of water rise. If I can find that, I will link it.
It is better for an overall view of what would occur then the first suggestion, but not very good if you want to see much detail.

A 20 feet rise is not the prediction. The Intergovernmental Panel on Climate Change (IPCC) hundred year guesstimate is in inches, not feet. The 20 ft number is Al Gore's theatrical fantasy.
To answer your question - a hypothetical 20 rise in sea level would move the shoreline an irregular amount. Places where the shoreline is steeply banked wouldn't see much difference. Flat places would see the shoreline move miles. Sorry, I don't have an estimate for the average.

The Intergovernmental Panel on Climate Change (IPCC) hundred year guesstimate is in inches, not feet...
True...
But then they didn't factor in any sea rise due to polar melting at all!!!
There is so much above ground ice on the poles that, if melted, will add to sea rise in ways the IPCC didn't even introduce into it's equations...
The answer for this requires a good GIS model but my guess is that it isn't a matter of inland so much as it is of just good old fashion altitude...
20 foot of sea rise would probably require you to be somewhere around 18 feet above sea level to stay dry...

That is an Al Gore prediction. All the geo-scientists that they had commenting on his claims on TV (even the liberal PBS) said it would rise about 1 foot in 3 centuries if the trend continues.

Anything that is 20 ft above sea level or below, will be under water. It all depends.
