Then you're pretty much out of luck.

Rich! Bull! That's _exactly_ what a planimeter does for a living!

No, it integrates surface area while measuring BOTH perimeter and angle
traveled from a single point, simultaneously. That makes a big
difference, although I still don't know exactly how they work. But,
they require you to stick a pin in the paper at one point and not move
it until you've traced the entire perimeter.
