Major radius = 45

Minor radius = 20

(x^2)/(45)^(2) + (y^2)/(20)^(2) = 1

You're correct. Was trying to answer before wireless service ran out. Thanks for the correction which I will now apply.

I don't think this is correct, George.

The standard form of an ellipse is

x^2/a^2 + y^2/b^2 = 1, where a and b are the radii in the corresponding directions.

So for this problem, with a = 45, b = 20.

x^2/45^2 + y^2/20^2 = 1
