61. I find it helpful to think of a polygon's perimeter as the
length of its boundary.
62. If a polygon is not regular, I can determine the sum of the
measures of its angles, but not the measure of any one of its
angles.
63. I used floor tiles in the shape of regular pentagons to
completely cover my kitchen floor.
In Exercises 64-65, write an algebraic expression that represents
the perimeter of the figure shown.
