Draw 99 circles in a row, then draw a separate polygon around each one with only a teeny amount of excess area, then connect those polygons with teeny little connectors to make it a single polygon. When I say "teeny", you can make those arbitrarily small, so you can certainly fit them under 1 total area.
Okay, it's maybe not "obvious" in a regular human sense, but in a graduate math class you could claim this was "obvious". It would be pretty clear if I were drawing a diagram on a whiteboard. I would definitely take less time proving this to a human, than formalizing it.
