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 10. The second vertex is at the top of row 4 and the left of column 1. The third vertex is at the bottom of row 10 and the right of column 10.
What is the area of the non-right triangle? The base and height are found by counting the squares.

The base of the triangle is 10 units and the height is 7 units. Therefore, the area of the triangle is (1/2) * base * height = (1/2) * 10 * 7 = 35 square units.
