The formula for the area of a trapezoid treats the distance between the parallel sides as the height. Doing this lists the height as 4m.
B
You can separate a trapezoid into a rectangle with a width of 3 and a height of 4, as well as a right triangle with a width of 2 and a height of 4.
C
This expression is the written out portion of separating the trapezoid into a triangle and rectangle.
(3 * 4) represents the rectangle and (1/2 * 2 * 4) represents the triangle.
D
The area as found by the accurate expression in part C is 16.
