To calculate the area of a triangle, you can use the formula:
\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]
From your description, it seems you have a triangle on a grid where you can count the number of squares to find the base and height.
- Count the base: Identify the length of the base of the triangle in terms of grid squares.
- Count the height: Identify the height of the triangle in terms of grid squares, which is perpendicular to the base.
Once you have the base and height, substitute these values into the formula to get the area.
Since I can't see the image you mentioned, I'm unable to calculate the base and height for you. However, looking at the area options you provided, you can determine the area based on your counts. Simply calculate the area using the formula above with your counted values for base and height.
If you provide the specific base and height values, I can help you calculate the area!
