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 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.

What is 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 6 units (from column 1 to column 7) and the height is 4 units (from row 2 to row 10).

Area = 1/2 * base * height
Area = 1/2 * 6 * 4
Area = 12 square units

Therefore, the area of the non-right triangle is 12 square units.
