Create your own real world problem that involves designing a 2D shape. Then: write an expression to find the perimeter of that design.
A square with 20 ft sides is put on the moon
What is the perimeter?
sides = s
s x 4/4 = 20
s = 20
s x 4 = 80
Create an extension problem that builds on your story problem. (like a part B for your story problem)
