The base of the triangle is 3 squares (from column 1 to column 4) and the height is 6 squares (from row 2 to row 10).
Therefore, the area of the non-right triangle is (1/2) x base x height = (1/2) x 3 x 6 = 9 square units.
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 at the top of row 2 and the right of column 8. The second vertex is at the top of row 4 and the right of column 1. The third vertex is at the bottom of row 10 and the right of column 8.
What is the area of the non-right triangle? The base and height are found by counting the squares.
