Answer :

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

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

Given:
- The base of the triangle is 9 inches.
- The height of the triangle is 3 inches.

Step-by-step solution:

1. Identify the base and height:
- Base ([tex]\(\text{b}\)[/tex]) = 9 inches
- Height ([tex]\(\text{h}\)[/tex]) = 3 inches

2. Substitute the base and height into the formula for the area of a triangle:
[tex]\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \][/tex]

3. Perform the multiplication inside the formula:
[tex]\[ \text{Area} = \frac{1}{2} \times 9 \times 3 \][/tex]

4. First, multiply the base and the height:
[tex]\[ 9 \times 3 = 27 \][/tex]

5. Next, multiply the result by 1/2:
[tex]\[ \frac{1}{2} \times 27 = 13.5 \][/tex]

Thus, the area of the triangle is [tex]\( 13.5 \)[/tex] square inches.
