Answer:
C. 18 inches
Step-by-step explanation:
The median of a trapezoid is the line segment that joins the midpoints of the sides of the trapezoid. It is halfway between the parallel bases, and is parallel to them. It length is the average of the lengths of the two bases:
(15 +21)/2 = 36/2 = 18 . . . . inches
So attached is the plotting of the triangle and I estimated it's area to be 7 squared units (OPTION C).
Note: in the graph i used colour codes to represent those partial squares that I used to counted as one and the gray squares are the naturally whole ones.
Hope this helps
