The area of a trapezoid is as follows:
A =

A and B are the lengths of the parallel lines of trapezoids. The parallel lines in this problem are 3.5 and 9.2. After adding those and dividing by 2, we multiply 17 to find the area of the trapezoid. (This is also shown in the attached picture)
The number line M-N is from 0 - 9.
2/3 of the way will be the same as 9 x 2/3
That equals 18/3 which reduces to 6.
6 is the coord 2/3 across the numberline from 0 to 9.
