Hector designs a piece of jewelry show before. All lengths are marked in centimeters what is the total area of the piece of jewelry
The triangle has an height of 3cm and base of 2cm
The other triangle has a height of 2cm and base of 9 cm
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.

The total area of the piece of jewelry is 12 square centimeters (12 cm²).
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 correct option is 12 square centimeters.
