Hey Fellows,

I am having trouble coming up with a solution of a problem related to area, popoulation, and Number of Houses. So here's what I am trying to do.

I have:

Area of a City

Population of a City

Number of Buildings in a City

Based on this information I want to approximate few scenarios based on flooding. Lets say the city is flooded and significant portion of the city is under water. I know how much area is lost due to flooding. So how can I then approximate the number of people who are affected and number of buildings which are under water? Is there any mathetical name for problem as such, and what kind of formula, function or method would you recomend?

Any help will be appreciable.

Regards.
