Verified Answer :

Answer:

Option D 14 units.

Step-by-step explanation:

In the given diagram a trapezoid has been given with two bases AB = 7 units and CD = 21 units

We have to find the median of the trapezoid. We know that median of a trapezoid is half of the sum of bases.

So median of ABCD = \(\frac{1}{2}\) (AB + CD)

                                 = \(\frac{1}{2}\) ( 7 + 21 )

                                 = \(\frac{1}{2}\) ( 28 )

                                 = 14 units.

Option D 14 units is the answer.
