Perimeter: Add up the length of all the sides. Area: You have to learn formulae for different figures, and apply them. For a rectangle, you just multiply length x side. For other figures, use other formulae. For example, the area of a triangle is 1/2 x base x height (where the height is perpendicular to the base).
