To find the area of the non-right triangle, we need to calculate the base and height of the triangle by counting the squares.
The base of the triangle is 6 squares horizontally, and the height of the triangle is 9 squares vertically.
Therefore, the area of the triangle is (1/2) * base * height = (1/2) * 6 * 9 = 27 square units.
Therefore, the correct answer is not provided in the options given. The closest option is 28.5 square units, but the correct answer should be 27 square units.
