Sam Azucena is 6-feet tall. He is the tallest person in his family. It just so happens that Sam learned the important principle of the 2:1 relationship just prior to his family's decision to purchase a mirror that was to be used by the entire family. Sam decided to put it to
good
use. Sam convinced his parents that it would be a waste of money to buy a mirror longer than 3 feet. "After all," Sam argued, "I'm the tallest person in the family and only three feet of mirror would be required to view my image." Sam's parents conceded and they purchased a 3-foot tall mirror and mounted it on the bathroom wall.
