The area, a, of an ellipse can be determined using the formula a=ttxy where x and y are half the lengths of the largest and smallest diameters of the ellipse. which is an equivalent equation solved for y

Area of an ellipse(a), ,having x and y being the  lengths of the largest and smallest diameters of the ellipse = π xy

  The  lengths of the largest and smallest diameters of the ellipse is called Major Axis and Minor axis of the ellipse.
