The area \( A \) of a right triangle can be calculated using the formula:
\[
A = \frac{1}{2} \times \text{base} \times \text{height}
\]
In this case, the base is 4.25 inches and the height is 11 inches. Plugging in these values:
\[
A = \frac{1}{2} \times 4.25 \times 11
\]
First, we calculate \( 4.25 \times 11 \):
\[
4.25 \times 11 = 46.75
\]
Now, we can find the area:
\[
A = \frac{1}{2} \times 46.75 = 23.375
\]
Thus, the area of the right triangle is:
\[
\boxed{23.375} \text{ square inches}
\]
