Given:


A=(1)/(2)h(b_1+b_2)

To determine h, we first multiply both sides by 2:


\begin{gathered} A(2)=(1)/(2)h(b_1+b_2)(2) \\ Simplify \\ 2A=h(b_1+b_2) \end{gathered}

Next, we divide both sides by (b1+b2):


\begin{gathered} (2A)/((b_1+b_2))=(h(b_1+b_2))/((b_1+b_2)) \\ Simplify\text{ and rearrange} \\ (2A)/((b_1+b_2))=h \\ h=(2A)/(b_1+b_2) \end{gathered}

Therefore, the answer is:


h=(2A)/(b_(1)+b_(2))
