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.

The base of the triangle is from column 1 to column 10, which is 10 units. The height of the triangle is from row 3 to row 10, which is 7 units.
Therefore, the area of the triangle is (1/2) x base x height = (1/2) x 10 x 7 = 35 square units.

The base of the triangle is from column 1 to column 7, which is 7 units. The height of the triangle is from row 2 to row 10, which is 8 units.
Therefore, the area of the triangle is (1/2) x base x height = (1/2) x 7 x 8 = 28 square units.
its wrong
I apologize for the error in my previous response. Let's correct the calculation.
The base of the triangle is from column 1 to column 7, which is 7 units. The height of the triangle is from row 2 to row 10, which is 8 units.
Therefore, the area of the triangle is (1/2) x base x height = (1/2) x 7 x 8 = 28 square units.

An illustration shows a 6 by 8 grid labeled Triangle C. Triangle C is graphed on the grid. The base of the triangle is labeled b equals 6.
An illustration shows two 6 by 8 grids with a rectangle graphed on each grid. The grid on the left is titled Figure A. The grid on the right is titled Figure B. The rectangle in Figure A is divided into two triangles by a diagonal line from the top right corner to the bottom left corner. The triangle on the left is labeled triangle A. The rectangle in Figure B is divided into two triangles by a diagonal line from the top right corner to the bottom left corner. The triangle on the right is labeled triangle B.
Are Figure A and Figure B the correct decomposition of triangle C?
Choose 1 for Yes or 2 for No.

No
wrong
Apologies for the mistake.
Yes, Figure A and Figure B are the correct decompositions of Triangle C.
Triangle C can be split into two triangles using a diagonal from the top right corner to the bottom left corner, as shown in Figure A and Figure B.
Triangle C has a base of 30 feet and a height of 6 feet. Model the area equation for the triangle by decomposing and rearranging to find the area of triangle C .(1 point)
The area of triangle C is
square feet.
