An outdoor racetrack is shaped like an ellipse. the equation of the outer lane is x2/6562 + y2/1444 . each lane is approximately 1 meter apart. find the length and width of the inner lane, as indicated in the figure. assume that the center is located at (0,0) , that the track is a horizontal ellipse, and that one meter is equivalent to one coordinate unit. a. length = 81 m width = 38 m b. length = 158 m width = 72 m c. length = 160 m width = 74 m d. length = 162 m width = 76 m
