What is the length of the midsegment of this trapezoid? Enter your answer in the box. units Trapezoid A B C D on the coordinate plane. The vertices of the trapezoid are A begin ordered pair negative 11 comma 3 end ordered pair, B begin ordered pair 0 comma 3 end ordered pair, C begin ordered pair negative 1 comma negative 2 end ordered pair, and D begin ordered pair negative 8 comma negative 2 end ordered pair.

  9 units

Step-by-step explanation:

The top base has a length that is the difference between the x-coordinates of points A and B:

  0 -(-11) = 11

The bottom base has a length that is the difference between the x-coordinates of points C and D:

  -1 -(-8) = 7

The mid-segment has a length that is the average of the base lengths:

  (11 +7)/2 = 18/2= 9 . . . units; midsegment length
