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)
To find the area of the triangle, we need to find the base and height first.
The base is the distance between the first and second vertices. Counting the squares horizontally, we find that the base is 6 units.
The height is the distance from the third vertex to the line that contains the base. Counting the squares vertically, we find that the height is 8 units.
Now, we can calculate the area of the triangle:
Area = 1/2 * base * height
Area = 1/2 * 6 * 8
Area = 24 square units
Therefore, the area of the non-right triangle is 24 square units.
