Hector designs the piece of jewelry shown below. All lengths are marked in centimeters. What is the total area of the piece of jewelry? (1 point) ( measurements to use are 3cm, 2cm, 9cm, 2cm)
39 square centimeters
27 square centimeters
33 square centimeters
30 square centimeters
To find the total area of the piece of jewelry, we need to calculate the area of each shape and then add them together.
Rectangle A: 3cm x 2cm = 6 square cm
Rectangle B: 9cm x 2cm = 18 square cm
Rectangle C: 3cm x 2cm = 6 square cm
Total area = 6 + 18 + 6 = 30 square cm
Therefore, the total area of the piece of jewelry is 30 square centimeters.
Answer: 30 square centimeters
