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.
