Answer 1

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

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

Plugging in the values from your question:

- Base = 10.5 inches
- Height = 4 inches

\[
\text{Area} = \frac{1}{2} \times 10.5 \times 4
\]
\[
= \frac{1}{2} \times 42
\]
\[
= 21 \text{ square inches}
\]

Therefore, the area of the triangle is **21 square inches**.
