Lesson 2-2 Example 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.

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

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

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