To find the total area, we need to calculate the area of each component and then add them together.
1. The area of the rectangle on the left:
Length = 9 cm
Width = 2 cm
Area = length x width = 9 cm x 2 cm = 18 cm²
2. The area of the rectangle in the middle:
Length = 3 cm
Width = 2 cm
Area = length x width = 3 cm x 2 cm = 6 cm²
3. The area of the rectangle on the right:
Length = 2 cm
Width = 2 cm
Area = length x width = 2 cm x 2 cm = 4 cm²
Total area = 18 cm² + 6 cm² + 4 cm² = 28 cm²
Therefore, the total area of the piece of jewelry is 28 cm².
9 cm
2 cm
3 cm
2 cm
