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 7. The second vertex is at the top of row 2 and the right of column 1. The third vertex is at the top of row 10 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.
(1 point)
The area is
square units.

The base of the triangle is 6 units (from column 1 to column 7) and the height is 8 units (from row 2 to row 10).
Therefore, the area of the non-right triangle is (1/2) * base * height = (1/2) * 6 * 8 = 24 square units.
