Use the image to answer the question. An illustration shows a 5 by 10 grid labeled Triangle C. Triangle C is graphed on the grid. Use decomposition and rearranging to model the area formula of triangle C. What is the area of triangle C in square units? (1 point)
40 square units
20 square units
80 square units
20 units
To find the area of Triangle C, we can rearrange it into a rectangle by decomposing it and moving the right triangle on top of the left triangle. This will create a rectangle that is 5 units by 10 units.
The formula for the area of a rectangle is length * width. In this case, the length is 10 units and the width is 5 units.
Area = length * width
Area = 10 * 5
Area = 50 square units
Therefore, the area of Triangle C is 50 square units. None of the provided options are correct, so the closest answer would be 40 square units.
