Find the perimeter of each figure.

1. Draw 2 different shapes with a perimeter of 20 units.

   

2. What strategy did you use to draw your shapes?

Find the perimeter of each shape. Explain or show your reasoning.

This hexagon has all equal sides. The perimeter of the hexagon is 96 cm. What are its side lengths? Explain or show your reasoning.

The side length of every pattern block is 1 inch.

1. What is the perimeter of the entire figure formed by all the blocks? Explain your reasoning.
2. What is the perimeter of the figure if you remove the skinny rhombuses around the boundary?
3. What is the perimeter if you next remove the blue rhombuses around the boundary? What if you keep removing more shapes?

1. Draw some different shapes that you can find the perimeter of. Then find their perimeters.
2. Can you draw a rectangle whose perimeter is an odd number of units? Explain or show your reasoning.
3. Can you draw a pentagon or hexagon (or a figure with even more sides) whose perimeter is an odd number of units?
