Perimeter is the distance around something, like how much space you need to walk all the way around a toy block.
Imagine you have a rectangular cookie sheet in front of you, it’s flat and has four sides. If you wanted to put a tiny fence all the way around it, so no cookie can escape, the length of that fence would be the perimeter of the cookie sheet.

Think about drawing a picture with crayons on paper. If you use a marker to go along the edges, top, bottom, left, and right, that line you draw is like the perimeter. It shows how long the edge is all around your shape.
If the cookie sheet is 10 inches long and 6 inches wide, then walking around it would mean going 10 + 6 + 10 + 6 = 32 inches in total, that's its perimeter!
You can find perimeter for any shape by adding up all the sides. It’s like counting steps as you walk around something fun!
Examples
- A garden has a fence around it, the length of that fence is its perimeter.
- Imagine walking all the way around your classroom, that path you walked is the perimeter.
- If you have a rectangular table, the total distance around the edges is the perimeter.
