For your next question on vectors, you will have to brief us as to what you have learned. To combine two vectors, you could use graphical methods or summing components of vectors.
In this particular case, since the two vectors happen to be directed opposite to each other, we only have to use scalar addition, with the positive sign towards east, and negative towards West.
Thus the resultant is
=+48-21 cm towards East
=27 cm towards East.
