How do you find the perimeter and are of a triangle on a coordinate graph?

Question

Well, the perimeter is the length of all of the sides added together.  If you know two of the side lengths you can calculate the third.

The area is defined as b*h/2 where b is the base, or the length of one side, and h is the height (the line that would be made if you drew a line at a 90 degree angle from the base such that it goes through the angle.  If you would like I could draw a picture to show you how to do this.
