Think about the Base Ten blocks you used during the lesson. Using $1$ hundred block, $3$ ten blocks, and $6$ one blocks, create a shape with the largest possible perimeter. Remember that the blocks need to be touching along a side, not connected at a corner. Sketch your solution and show all of your work.

Help:

A reminder: The perimeter is the sum of the lengths of a shape's sides. Be sure to make the longer sides of the blocks exposed to increase the perimeter.

Answer:
