To calculate the total area of the piece of jewelry, we need to find the area of each rectangle and then add them together.
Rectangle 1: 9 cm x 2 cm = 18 square cm
Rectangle 2: 3 cm x 2 cm = 6 square cm
Rectangle 3: 2 cm x 2 cm = 4 square cm
Total area = 18 + 6 + 4 = 28 square centimeters
Therefore, the total area of the piece of jewelry is 28 square centimeters.
