Depending upon the shape, usually you can break it down into smaller shapes -- rectangles or even triangles that you can take the area of and then sum up the areas of the smaller shapes.

If it is a curved shape and not a conic (circle or ellipse), you'd need integral calculus which, by the way, is based on breaking the shape up into infinite number of rectangles.

Perimeter is just the distance around the shape.  So, you'd just add together all of the side lengths.
