To calculate the area of a triangle on a coordinate grid, you can use the formula:
\[ \text{Area} = \frac{1}{2} \left| x_1(y_2-y_3) + x_2(y_3-y_1) + x_3(y_1-y_2) \right| \]
You will need the coordinates of the three vertices of the triangle to apply this formula. Unfortunately, since I cannot see images, you will need to provide the coordinates of the triangle's vertices to calculate the area accurately. Please provide that information, and I can help you find the area!
