To find the area of triangle ABC, we need to know the lengths of its base and height. However, the figure to the right is not provided, so we can't directly determine the lengths of any sides or heights.
If you have the figure, you can find the answer by using the formula for the area of a triangle, which is (base * height) / 2. The base of triangle ABC is the same as the length of side AB of the rectangle, and its height is the perpendicular distance from AB to line CD.
If you do have the figure, follow these steps to find the area of triangle ABC:
1. Measure the length of side AB of the rectangle.
2. Measure the perpendicular distance from AB to line CD. This can be done by drawing a line segment perpendicular to AB from point C or D, and measuring that line segment.
3. Multiply the length of side AB by the perpendicular distance found in step 2.
4. Divide the result by 2 to find the area of triangle ABC.
Since the figure is not provided here, I'm unable to perform the calculations or provide a numerical answer.
