Answer:
20 cm
Step-by-step explanation:
We are given a trapezoid, where the length of shorter base or on of the parllel line is 16 cm and the length of other parallel side is 24 cm.
Let the two parallel sides be x and y that is x = 16 cm and y = 24 cm.
A median of a trapezoid is a line segment that divides the non parallel sides of a trapezoid equally or a line segment that passes through the mid points of non-parallel sides of a trapezoid.
The length of median of a trapezoid =
=
= 20 cm.
Thus, the length of median of trapezoid is 20 cm.

Step-by-step explanation:
The given points are A(1,2,3), B(-2,0,5) and C(4,1,5). The triangle is represented in the attach file where the three possible median are length AE, BF, and CD. We determine the coordinate of point D,E and F using the midpoint equation which is for any point A(x,y,z) and point B(a,b,c), the midpoint D is determine by
.
Hence going by the above formula we determine the coordinate of point D,E and F

.
To determine the length of each median line we use the formula for distance between two points which is express as
.
Using the above formula we determine the length of line AE,BF and CD.
