Perimeter

Walt: measure the perimeter using a ruler.

I remember that perimeter is the area around the shape. You would use perimeter when measuring furniture to put into clear spaces. Area is the surface of the specific shape. You would use area when building houses. I have a good understanding of area and perimeter. To extend my learning about perimeter and area I should do more complex examples.
