Answer:
The resultant for given Vector A is (6, 4) and Vector B is (-2, -1) is 9.43. 
Step-by-step explanation:
The quantities which have both magnitude and direction is called vector.
The resultant is given by the formula: 

Where, 
R is resultant of the vectors A and B 
 ,
, 
 ,
, 
 , and
, and 
 are the vertices of vectors.
 are the vertices of vectors. 
Given that: 




On substituting the given values in the above mentioned equation. 





Therefore, resultant is 9.43 for the given vectors A and B.
