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.
