Answer:

b2 = 2A/h -b1

Step-by-step explanation:

The usual formula for the area of a trapezoid is ...

$A=\dfrac{1}{2}(b_1+b_2)h$

We can solve this for b2:

$\dfrac{2A}{h}=b_1+b_2 \qquad\text{multiply by $\dfrac{2}{h}$}\\\\ \dfrac{2A}{h}-b_1=b_2 \qquad\text{subtract $b_1$}\\\\ \boxed{b_2=\dfrac{2A}{h}-b_1}$
