Question

A=1/2h(b1+b2) Please solve for b2

Answer 1

Answer:

$\displaystyle b_2=\frac{2A}{h}-b_1$

Step-by-step explanation:

Equation Solving

Given the formula:

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

It's required to solve it for b2.

First, we eliminate denominators by multiplying by 2:

$\displaystyle 2A=h(b_1+b_2)$

Divide by h:

$\displaystyle \frac{2A}{h}=b_1+b_2$

Subtract b1:

$\displaystyle \frac{2A}{h}-b_1=b_2$

Write the new formula:

$\boxed{\displaystyle b_2=\frac{2A}{h}-b_1}$
