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 are found by counting the squares.

Answer 1

The base of the triangle is 5 units (from column 4 to column 9) and the height of the triangle is 7 units (from row 2 to row 9).

Area = 0.5 * base * height
Area = 0.5 * 5 * 7
Area = 17.5 square units

Therefore, the correct answer is 17.5 square units.
