3.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
a
square units.
The base of the triangle is 9 squares and the height is 6 squares.
Therefore, the area of the triangle is:
Area = 1/2 x base x height
Area = 1/2 x 9 x 6
Area = 1/2 x 54
Area = 27 square units
So, the area of the non-right triangle is 27 square units.
