The formula for the area of the shape really depends on the shape. Some of the following are the areas of certain shapes:

Rectangle area = lw (length x width)

Parallelogram area = bh (base x height)

Triangle area = 1/2 bh

Trapezoid area = [(b1 + b2)/2] h

There are other shapes as well that require different formulas for finding their area.
