To calculate the area of a triangle on a coordinate grid, you can use the following formula based on the coordinates of the vertices of the triangle:
If the triangle has vertices at \((x_1, y_1)\), \((x_2, y_2)\), and \((x_3, y_3)\), then the area \(A\) can be calculated using the formula:
\[ A = \frac{1}{2} \left| x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2) \right| \]
To answer the question specifically, you will need to provide the coordinates of the vertices of the triangle. If you can provide those coordinates, I would be able to calculate the area for you.
