Blue is a circle
Red is an ellipse
Black lines are common tangents

What I have
1- Parameter equation for both ellipse and circle (with centre point known of course)

Area of circle = C
Area of ellipse = E
Area of black, extended to make a full triangle, = T
(A+C+T) - .5(A) - .5(C)

Rewrite equation as
(E+C+T) - .5(E) - .5(C)
