Answer:
[tex]\displaystyle h= \frac{2A}{a+b}[/tex]
Step-by-step explanation:
The given formula is:
[tex]\displaystyle A=\frac{h}{2}(a+b)[/tex]
We need to solve the formula for h.
Multiply by 2:
[tex]2A=h(a+b)[/tex]
Divide by (a+b)
[tex]\displaystyle \frac{2A}{a+b}=h[/tex]
The required solution is:
[tex]\displaystyle h= \frac{2A}{a+b}[/tex]
