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 1. The second vertex is at the bottom of row 10 and the right of column 1. The third vertex is at the top of row 5 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 base of the triangle is 9 squares and the height is 8 squares.
Therefore, the area of the triangle is (1/2) x base x height = (1/2) x 9 x 8 = 36 square units.
So, the correct answer is 36 square units.
