The area \( A \) of a triangle can be calculated using the formula:
\[
A = \frac{1}{2} \times \text{base} \times \text{height}
\]
In this case, the base is 5 inches and the height is 12 inches. Plugging in these values:
\[
A = \frac{1}{2} \times 5 \, \text{inches} \times 12 \, \text{inches}
\]
\[
A = \frac{1}{2} \times 60 \, \text{sq. in.}
\]
\[
A = 30 \, \text{sq. in.}
\]
Thus, the area of the triangle is **30 sq. in.** Therefore, the correct answer is:
**A) 30 sq. in.**
\[
A = \frac{1}{2} \times \text{base} \times \text{height}
\]
In this case, the base is 5 inches and the height is 12 inches. Plugging in these values:
\[
A = \frac{1}{2} \times 5 \, \text{inches} \times 12 \, \text{inches}
\]
\[
A = \frac{1}{2} \times 60 \, \text{sq. in.}
\]
\[
A = 30 \, \text{sq. in.}
\]
Thus, the area of the triangle is **30 sq. in.** Therefore, the correct answer is:
**A) 30 sq. in.**
