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 1 and the right of column 3. The second vertex is at the top of row 7 and the left of column 1. The third vertex is at the top of row 1 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 area of the non-right triangle is 27 square units.
To calculate the area, we can first find the base and height of the triangle:
Base: 9 units
Height: 6 units
Then, apply the formula for the area of a triangle:
Area = 0.5 x base x height
Area = 0.5 x 9 x 6 = 27 square units
Therefore, the correct answer is 27 square units.
