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

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

(1 point)
The area is blank square units.

We cannot determine the area without knowing the exact measurements of the base and height of the triangle.

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 8 and the right of column 1. The third vertex is at the top of row 10 and right of column 10.

What is the area of the non-right triangle? The base and height are found by counting the squares.
To find the area of the triangle, we need to find the base and height. We can count the number of squares in each row and column to determine the distance between the vertices.

The base of the triangle is 6 squares wide (from column 1 to column 6), and the height is 2 squares high (from row 2 to row 4).

Therefore, the area of the triangle is:

(1/2) x base x height
= (1/2) x 6 x 2
= 6 square units

So, the area of the non-right triangle is 6 square units.
