For twenty, complete the figure by extending the parallel line to y. You now have a rectangle with area 3y. This should be quite apparent from the answer choices.

Of course, the harder part is to define the area of the triangle. What can you say about the triangle with an angle of 45 degrees and one of 90? This should help identify the “extension” of the line as being the same as x. Now you have a triangle with area of 1/2 x^2.

Check if one answer matches the total of the triangle and the rectangle 3x.
