In this case, we need to find the area of the non-right triangle by calculating the area of the rectangle formed within the grid and subtracting the areas of the three right triangles outside of the non-right triangle.
The rectangle has dimensions of 9 by 6, so its area is 9 x 6 = 54 square units.
The three right triangles have base and height dimensions of (6 x 2)/2 = 6, (10 x 1)/2 = 5, and (10 x 1)/2 = 5, so their total area is 6 + 5 + 5 = 16 square units.
Thus, the area of the non-right triangle is 54 - 16 = 38 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 is at the top of row 2 and the right of column 6. The second vertex is at the top of row 8 and the right of column 1. The third vertex is at the top of row 10 and right of column 10.
What is the area of the non-right triangle? The base and height are found by counting the squares.
