For an ellipse given two foci, each a distance, c, from the center of the ellipse and the two foci are along the line of the major axis.The distance from the focus of an ellipse, from the center of the ellipse is given bywhere: a is the length of the major axis and b is the length of the minor axis.Therefore, therefore, the distance of the two foci is given by2c = 2(12) = 24 feet.
