Ant's Edge Walk
What is the perimeter of a shape and how do we find it?
Imagine a tiny ant who decides to take a walk all the way around the edge of a shape — never cutting across the middle, just hugging the outline like a fence. The total distance that ant walks? That's the perimeter. It's simply the length of the whole way around.
