To calculate the area of a triangle, you can use the formula:
\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]
In this case, you mentioned that the base of the triangle consists of 6 angled squares. Assuming each square represents 1 square unit, the base length is 6 units.
Next, you need to determine the height of the triangle. If the height is also determined by counting squares on the grid, you will need that specific value to proceed with the calculation.
If you can provide the height value, I can help you calculate the area accurately. Without the height, I can't determine the area from the options you've given. Please provide the height of the triangle.
