Step1: Recall ellipse property

The sum of the distances from any point on an ellipse to the two foci is equal to the length of the major - axis.
The red and blue line - segments represent the distances from a point on the ellipse to the two foci.
Since the length of the major axis is 13, the sum of the red and blue line - segments is also 13.
