1. Lesson 2-2 Example 4 2-2 Kaliska is playing a board game with her family. A $5 bill of the play money has two sides with a length of 12 centimeters and two sides with a width of 4 centimeters. What is the perimeter of a $5 bill? Understand Read the problem. Write what you know. A $5 bill has two sides that are 12 centimeters long and two sides that are 4 centimeters long.

2. Lesson 2-2 Example 4 2-2 Plan Pick a strategy. One strategy is to draw a diagram.

3. Lesson 2-2 Example 4 2-2 Solve Add the lengths of the sides to find the perimeter. 12 + 12 + 4 + 4 = 32 The perimeter of a $5 bill is 32 centimeters.

4. Lesson 2-2 Example 4 2-2 Check Use the formula. (2  12) + (2  4)= (24)+ (8)= 32 (2  length) + (2  width) = perimeter of a rectangle
