To find the total area of the piece of jewelry, we need to calculate the area of each triangle separately and then add them together.

For the first triangle:
Area = 1/2 * base * height
Area = 1/2 * 2cm * 3cm
Area = 3cm²

For the second triangle:
Area = 1/2 * base * height
Area = 1/2 * 9cm * 2cm
Area = 9cm²

Total area = 3cm² + 9cm²
Total area = 12cm²

Therefore, the total area of the piece of jewelry is 12cm².
