Question

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

Answer 1

`\displaystyle b_2=(2A)/(h)-b_1`

Explanation:

Equation Solving

Given the formula:

`\displaystyle A=(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 (2A)/(h)=b_1+b_2`

Subtract b1:

`\displaystyle (2A)/(h)-b_1=b_2`

Write the new formula:

`\boxed{\displaystyle b_2=(2A)/(h)-b_1}`
