Area Formulas Needed

Area = Length * Width

Area = Pi * A * B
Where Pi = 3.14159..
A = semi-major axis
B = semi-minor axis


semi-major axis: The major axis of an ellipse is its longest diameter. The semi-major axis is one half of the major axis, and thus runs from the center to the edge of the ellipse. For the special case of a circle, the semi-major axis is just the radius.

semi-minor axis: The minor axis of an ellipse is the longest line that runs perpendicular to the major axis. The semi-minor axis is one half of the minor axis.
