Answer:
4
Step-by-step explanation:
The distance from B to C is the same as the distance from A to D. Points B and C will both have the same x-value, as do points A and D. Points B and C will have the same difference in y-values (2 -(-2) = 4) that points A and D have.
The distance from B to C is 4 units.
Sqrt7 / sqrt 11 = sqrt7/11
