Perimeter: add the three sides.
Area: Use the formula area = (1/2) x base x height. Please note that the height must be measured perpendicular to the base. Depending on the data known, you might also use other formulae; for example, if you know the lengths of the three sides, you can use Heron's formula - if you need it, look it up on the Wikipedia.
