The perimeter of a figure is the distance all the way around the figure.
Area is how many units takes up the figure.
Example of perimeter: (attached)
Example of area: (attached, with squares in square)
In this case, the <em>area depends on the perimeter</em>. Count two sides of the rectangle. (Horizontal, and vertically.) Then write what the perimeter is for that. <u>Multiply</u> the two numbers and that will be your area.
Vertically, it is 11. Horizontally, it is 9. I would like you to try to see what to do next, if not, comment!
I hope this helped!
