To find the area of the triangle, we can use the formula: Area = 1/2 * base * height

First, we need to find the base of the triangle. We can see that the base is 6 units.

Next, we need to find the height of the triangle. We can extend a perpendicular line from vertex A to side BC in order to form a right triangle. By doing this, we create a right triangle with legs of 3 units and 5 units. Using the Pythagorean theorem, we find that the height is 4 units.

Now, we can calculate the area of the triangle:
Area = 1/2 * 6 * 4 = 12 square units

So the correct answer is: 12 square units.
