Answer 1

Answer:

The answer is h = 2A/(b+c) .

Step-by-step explanation:

You have to move all the unrelated terms to the other side by making h the subject :

$A = \frac{1}{2} (b + c)h$

$A \div \frac{1}{2} = \frac{1}{2} (b + c)h \div \frac{1}{2}$

$2A = (b + c)h$

$2A \div (b + c) = (b + c)h \div (b + c)$

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

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