Answer 1

To find the area of a triangle, you can use the formula:

\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]

For Hailey's ornament, the base is 7 cm and the height is 6 cm. Plugging in those values:

\[ \text{Area} = \frac{1}{2} \times 7 , \text{cm} \times 6 , \text{cm} = \frac{1}{2} \times 42 , \text{cm}^2 = 21 , \text{cm}^2 \]

So, the area of the ornament is 21 sq. cm.
