A=1/2h(B+b)
A=63
B=6
b=3
So... 63=1/2h(9)
....... Now what?

63=1/2 * h(9)
63 = 9h/2
h = 63 * 2/9
h= 14

A = 1/2h(B + b)
63 = 1/2(6 + 3)
63 = 1/2h(9)
63 = 9/2h
63 = 4.5h
63 / 4.5 = 4.5 h / 4.5
63 / 4.5 = h
14 = h

You're right so far.
Multiply both sides by 2.
63 * 2 = h(9)
Now divide both sides by 9
h = 63* 2 / 9 = 14

63=1/2h(9)
63=4.5h
63/4.5=h
14=h

63=(1/2)h(9)
multiply both sides by 2
126=9h
divide both sides by 9
14=h
h=14
h was unknown and now it is known.
