one approach
you have the coordinates plot the points draw the figure.
use the distance formula (pythagorean theorem) to find all the lengths that are not on the same horizontal or vertical line.  horizontal line the distance is the change in the x values there is no change in the y value; vertical line the distance is the change in the y values, there is no change in the x value. 
whatever figure you have can usually be seen as triangles and rectangles. 
the area of the figure is the sum of the area of all the triangles and rectangles you "divided" the figure into.
area of a circle = pi * r^2 where r is the radius
area of a triangle = 1/2 * base * perpendicular height
area of a rectangle = length * width
a square is a special rectangle where the length = width 

this should be more than enough to work with if you need more help
post a particular problem and I will go through it with you
