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 3 and the right of column 3. The second vertex is at the bottom of row 10 and the left of column 1. The third vertex is at the bottom of row 10 and the right of column 10.

(1 point)
The area is
square units.

Answer 1

The base of the triangle is 2 squares and the height is 7 squares.

Area = 0.5 x base x height
Area = 0.5 x 2 x 7
Area = 7 square units

Therefore, the area of the non-right triangle is 7 square units.
