Solve.Elaine has a grassy patch of land on her farm that is a rectangle measuring 50 feet by 80 feet. So her goat can eat grass while Elaine is busy with other farm work, she drove two posts into the ground and fastened a rope to each post, passing the rope through a metal ring on the goat's collar. When the goat pulls on the rope while walking, its path is an ellipse. (See the figure.) If the goat can just reach all four sides of the rectangular patch, find the equation of the elliptical path.
