Answer:
Answer is 19.5 units
Explanation:
Given that there is a trapezoid.
Its bases are 13 and 26 respectively.
Non parallel sides are congruent
To find the median that is the length of line connecting the midpoints of the non parallel sides
If we draw any one diagonal we see that median is the line connecting the mid point of two triangles with the parallel sides as bases
Hence length of median= 1/2 (base 1+base 2)
(By triangle mid point theorem)
= 1/2 (13+26)
=19.5 units
