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
square units.
Area = 1/2 * base * height
Base = 10 - 1 = 9 units
Height = 10 - 4 = 6 units
Area = 1/2 * 9 * 6 = 27 square units
Therefore, the area of the non-right triangle is 27 square units.
