Perimeter is the distance around the outside of a shape. It is calculated by adding up the lengths of each side of the shape. Perimeter is a useful tool for measuring the size of a shape or area, and can be used to calculate the size of a garden, the length of a fence, or the size of a room.

A perimeter calculator is a tool used to calculate the perimeter of a shape. It can be used to calculate the perimeter of a square, rectangle, triangle, circle, or any other shape. It can also be used to calculate the perimeter of a complex shape made up of multiple shapes.
