Question

Area of triangle: A=1/2bh; Solve for b.

Answer 1

As given 

$A = \frac{1}{2} * b* h$

Firstly we will multiply both sides by 2.

$2*A = 2* \frac{1}{2} * b * h$

$2A = bh$

Now dividing both sides of equation from h.

$\frac{2A}{h} = \frac{bh}{h}$

$\frac{2A}{h} = b$

So b =  $\frac{2A}{h}$

Answer 2

Answer: B=2a/h
