    If I read this correctly, the question is "What is the width of when the height is 10 units above the origin," which is somewhat of a confusing question.

    10 units above the origin is point (0,10) which has x=0, and y=10.

    Is the height, h = the vertical distance between the x axis and the center of the ellipse?

    Anyway, is the width considered the major axis or minor axis?

    One can solve for either.
