Question

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 7. The second vertex is at the top of row 2 and the right of column 1. The third vertex is at the top 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.

(1 point)

Answer 2

The base of the triangle is 6 squares (from the right of column 7 to the right of column 1), and the height is 8 squares (from the top of row 2 to the top of row 10).

The area of the triangle is:
(1/2) * base * height
= (1/2) * 6 * 8
= 24 square units.

Therefore, the area of the non-right triangle is 24 square units.
