Answer:

Explanation:
we have
a(-2,4), b(4,3), c(4,-5), d(-2,-2)
step 1
Plot the vertices to better understand the problem
using a graphing tool
The graph in the attached figure
step 2
Find the mid-segment parallel to ad and bc
Note : The mid-segment is parallel to the parallel bases of trapezoid
Let
e ---> midpoint segment ab
f ---> midpoint segment cd
The formula to calculate the midpoint between two points is equal to

Find the midpoint e
we have
a(-2,4) and b(4,3)
substitute the given values


Find the midpoint f
we have
c(4,-5), d(-2,-2)
substitute the given values


step 3
Find the length of the mid-segment ef
we have


the formula to calculate the distance between two points is equal to

substitute
