The area \( A \) of a triangle can be calculated using the formula:
\[
A = \frac{1}{2} \times \text{base} \times \text{height}
\]
Given that the base is 7 inches and the height is 14 inches, we can substitute these values into the formula:
\[
A = \frac{1}{2} \times 7 \, \text{in} \times 14 \, \text{in}
\]
Calculating this gives:
\[
A = \frac{1}{2} \times 7 \times 14 = \frac{1}{2} \times 98 = 49 \, \text{in}^2
\]
Therefore, the area of the triangle is \( 49 \, \text{in}^2 \).
The correct response is **49 in²**.
