Question

If
$a = \frac{1}{2} h(b _{1} + b _{2})$
Solve for
$h$
​

Answer 1

Answer:

$\large\boxed{h=\dfrac{2A}{b_1+b_2}}$

Step-by-step explanation:

$\dfrac{1}{2}h(b_1+b_2)=A\qquad\text{multiply both sides by 2}\\\\h(b_1+b_2)=2A\qquad\text{divide both sides by}\ (b_1+b_2)\neq0\\\\h=\dfrac{2A}{b_1+b_2}$
