~~~~~~~~~~~~~~~ 

The magnitude of the vector ML is the distance between the points M and L.


The x-component of the vector is  2 + 5 =  7  units long;  
the y-component of the vector is  8 + 2 = 10  units long.


Therefore, the magnitude of the vector ML is  sqrt%287%5E2+%2B+10%5E2%29 = sqrt%2849%2B100%29 = sqrt%28149%29 = 12.20656  (rounded).    ANSWER

Solved.
