A peninsula is a landform, not a geometric shape. It doesn't have "sides" in the way a polygon does.

Here's how to think about a peninsula:

* A peninsula is a piece of land that is almost entirely surrounded by water, but connected to a larger landmass.

* Think of it like a finger sticking out into the sea.

* The number of "sides" would depend on the specific shape of the peninsula, but that's not a useful way to describe it.
