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

Explanation:

Start by multiplying both sides by 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)#

Explanation:

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

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

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