The base of the triangle is 7 units (from column 1 to column 8) and the height is 6 units (from row 2 to row 10).
So, the area of the triangle can be calculated as:
Area = 1/2 * base * height
Area = 1/2 * 7 * 6
Area = 21 square units
Therefore, the area of the non-right triangle is 21 square units.
Question
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.
(1 point)
