For
Problems 44-51

Trace out the distance around each of the given figures. See Examples 2 and 3.
Problems 52-54

Choose the appropriate formula and calculate the answer. See Example 4.
**Note:** Homework Hints are given only for the Level 1 and Level 2 problems.

However, as you go through the book be sure you look at all the examples in the text. If you need hints for the Level 3 problems, check some sources for help on the internet (see the LINKS for that particular section. As a last resort, you can call the author at (707) 829-0606.

On the other hand, the problems designated “Problem Solving” generally require techniques that do not have textbook examples.
