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 4. The second vertex is at the top of row 9 and the right of column 4. The third vertex is at the top of row 6 and the right of column 9.
Find the area of the non-right triangle. The base and height are found by counting the squares.

The area of the non-right triangle can be calculated using the formula A = 0.5 * base * height. The base is 5 squares (column 9 to column 4 in row 6) and the height is 7 squares (row 9 to row 2).
A = 0.5 * 5 * 7
A = 0.5 * 35
A = 17.5 square units
Therefore, the area of the non-right triangle is 17.5 square units.
