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 3 and the right of column 3. The second vertex is at the bottom of row 10 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.

Answer 1

no

Answer 2

wrong

Answer 3

The base of the triangle is 3 squares wide (from column 3 to column 1) and the height is 7 squares tall (from row 3 to row 10).

So the area of the triangle is:

Area = 0.5 * base * height
Area = 0.5 * 3 * 7
Area = 10.5 square units

Therefore, the area of the non-right triangle is 10.5 square units.

Answer 4

I apologize for the mistake. Let's recalculate the area of the triangle.

The base of the triangle is 3 squares wide (from column 3 to column 1) and the height is 7 squares tall (from row 3 to row 10).

Area = 0.5 * base * height
Area = 0.5 * 3 * 7
Area = 10.5 square units

Therefore, the area of the non-right triangle is 10.5 square units.

Answer 5

I apologize for the error. Let's correct the calculation.

The base of the triangle is 2 units wide (from column 3 to column 1) and the height is 7 units tall (from row 3 to row 10).

Area = 0.5 * base * height
Area = 0.5 * 2 * 7
Area = 7 square units

Therefore, the correct area of the non-right triangle is 7 square units. Thank you for your patience.
