Perimeter of Polygons

The perimeter of a shape is the distance around the shape. It is calculated by adding together all the lengths of the sides of the shape.

For example, consider this shape:

Let's find its perimeter.

To find the perimeter, add the lengths of all the sides.

3 + 8 + 6 = 17

As the lengths are measured in kilometers, the perimeter is also measured in kilometers.

So, the perimeter of the given shape is 17 km.
