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 base of the triangle is 5 units (from column 1 to column 6) and the height is 8 units (from row 2 to row 10).
The area of the triangle is calculated as 0.5 * base * height = 0.5 * 5 * 8 = 20 square units.
Therefore, the correct answer is 20 square units.
