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 6 and the right of column 1. The third vertex is at the bottom of row 10 and the right of column 9.

What is the area of the non-right triangle? The base and height are found by counting the squares.

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 1. The second vertex is at the top of row 10 and the right of column 4. The third vertex is at the top of row 10 and the right of column 7.

Answer 1

The base of the triangle is 7 squares wide and the height is 8 squares tall.

The area of a triangle is calculated by multiplying the base by the height and dividing by 2.

Therefore, the area of the triangle is (7 * 8) / 2 = 28 square units.

So, the answer is:
28.5 square units
