I'm having trouble solving the following problem:
A local toy factory is making a new type of doll and are taking great care in creating the eyes. The crosshairs are centered at the center of the eye. The black part of the eye is tangent to the edge of the eye, and the horizontal crosshair crosses 9 millimeters of the white part of the eye, and the vertical crosshair crosses 5 mm of the white part of the eye on both the top and bottom. What is the area, in square millimeters, of the white part of the eye?
Here is the diagram for the problem:
