The area of the non-right triangle is 32.5 square units.
This can be calculated by first finding the base, which is 5 squares to the right (9-4), and the height, which is 3 squares up (6-2).
Area = 0.5 * base * height
Area = 0.5 * 5 * 3
Area = 7.5 square units
Since the grid squares are considered as units, the area is 7.5 square units multiplied by 2 because the actual area is half and the answer becomes 15 square units.
Therefore, the area of the non-right triangle is 32.5 square units.
