The formula entirely depends on the shape of the outline being considered.

A few examples include:

-- Circle . . . Area = (pi) (Radius)2

-- Square . . . Area = (length of one side)2

-- Rectangle . . . Area = (length) x (width)

-- Triangle . . . Area = 1/2 (length of the base) x (height)

Other shapes have different formulas.
