how to calculate the latitude line bisecting a polygon into half

I have a question about calculating the mean of a polygon based on its area.

Let's assume a polygon ranging from 0-3 degree in latitude.
The area ratio is as below.

area of 0-1 degree => 25% of the total area
area of 1-2 degree => 25% of the total area
area of 2-3 degree => 50% of the total area

Please kindly advise if there is any tool 
to obtain 2 degree in latitude, whose latitude line can cut the polygon into half based on area.
(ArcInfo 9.3 )

Thank you very much
