The length of the median (FE) is simply the sum of the midpoints:5.8 cm.
The median of a trapezoid is the segment connecting the midpoints of the non-parallel sides.
In this case, the non-parallel sides are WX and VY.
To find the length of the median (FE), we need to find the midpoints of WX and VY:
Midpoint of WX: (WX)/2 = 4.5 cm / 2 = 2.25 cm
Midpoint of VY: (VY)/2 = 7.1 cm / 2 = 3.55 cm
Therefore, the length of the median (FE) is simply the sum of the midpoints:
FE = 2.25 cm + 3.55 cm = 5.8 cm
