how do the find an area, in square units of a figure plotted on a graph?

Finding the area depends on the type of figure you have. Since this is not my area of expertise, I searched Google under the key words "area calculate" to get these possible sources:

http://www.renovationplanner.com/CalculateArea.shtml

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
