Answer:

3

Step-by-step explanation:

Midpoint between two lines is given by

x1+ x2/2; y1 + y2/2

midpoint between lines /AD/

x = x1+ x2/2 = -11 + (-8)/2 = -9.5

y = 3+ (-2)/2 = 3- 2/2 = 1/2 = 0.5

midpoint between lines /BC/

x = 0 + (-1)/2 = -1/2 = -0.5

y = 3+ (-2)/2 = 1/2 = 0.5

(x1,y1) = (-9.5, 0.5)

(x2,y2)= (-0.5,0.5)

the midsegment of the trapezoid ;

√(x2 - x1)² + (y2- y1)²

= √9
