Answer 1

The area of a triangle is given by the following formula:

$A=\frac{b\times h}{2}$

Where b is the length of the base and h is the height of the triangle.

In this case, the length of the base equals 8 inches and the height of the triangle equals 3 inches, by replacing 8 for b and 3 for h, we get:

$A=\frac{8\times3}{2}=\frac{24}{2}=12$

Then, the area of this triangle equals 12 square inches.
