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 4. The second vertex is at the top of row 9 and the right of column 4. The third vertex is at the top of row 6 and the right of column 9.

Find the area of the non-right triangle. The base and height

1 answer

To find the area of the non-right triangle, we can use the formula A = 0.5 * base * height.

The base of the triangle is the distance between the first and second vertices, which is 9 - 2 = 7 units.

The height of the triangle is the distance between the base (row 2) and the third vertex (row 6), which is 6 - 2 = 4 units.

Therefore, the area of the non-right triangle is:

A = 0.5 * 7 * 4
A = 14 square units.
