A=%281%2F2%29%2Abh

Clear the fraction by multiplying both sides by the denominator which is 2.
2%2AA+=+2%2A%281%2F2%29%2Abh
2A+=+bh

To solve for b, divide both sides by h:
%282A%29%2Fh=%28bh%29%2Fh
%282A%29%2Fh=b

For additional explanation on this topic of "Literal Equations", see my own website. Do a "Bing" or "Google" search for my last name "Rapalje". Look for "Rapalje Homepage" near the top of these searches. Then near the top of my Homepage, look for "Basic, Intermediate and College Algebra". Choose "Basic Algebra", "Chapter 3", "Section 3.07".
