Use the image to answer the question.
An illustration shows a 10 by 10 grid. A non-right triangle is enclosed within the grid. The first vertex is at the top of row 2 and the right of column 6. The second vertex is at the top of row 6 and the right of column 1. The third vertex is at the bottom of row 10 and the right of column 9.
What is the area of the non-right triangle? The base and height are found by counting the squares.

The area of the non-right triangle is 36.5 square units.
To calculate the area, you can use the formula:
Area = 0.5 * base * height
The base is 9 units (from column 1 to column 9) and the height is 8 units (from row 2 to row 10).
Area = 0.5 * 9 * 8 = 36 square units.
Therefore, the area of the non-right triangle is 36.5 square units.
