$h = \frac{2 A}{a + b}$ $h=(2A)/(a+b)$

Start by multiplying both sides by 2.

$2 \times A = 2 (\frac{h (a + b)}{2})$ $2xxA=2((h(a+b))/2)$

$2A=cancel2((h(a+b))/cancel2)$

$2A=h(a+b)$

Then divide both sides by (a+b)

$(2A)/(a+b)=(h(a+b))/(a+b)$

$(2A)/(a+b)=(hcancel((a+b)))/cancel((a+b))$

$(2A)/(a+b)=h$

$h=(2A)/(a+b)$

$h=(2A)/(a+b)$

$A=(a+b)/2 *h$

$2A=(a+b*h)$ multiply both sides by 2

$(2A)/(a+b)=h$ divide both sides by (a+b)
