As given 

[tex]A = \frac{1}{2} * b* h [/tex]

Firstly we will multiply both sides by 2.

[tex]2*A = 2* \frac{1}{2} * b * h [/tex]

[tex]2A = bh[/tex]

Now dividing both sides of equation from h.

[tex] \frac{2A}{h} = \frac{bh}{h} [/tex]

[tex] \frac{2A}{h} = b [/tex]

So b =  [tex] \frac{2A}{h} [/tex]
