Question

Herrons formula:2S=a+b+c solve for b

Answer 1

minus a and minus c from both sides

2S-a-c=b
b=2S-a-c

Answer 2

The value of the formula for b is
`2S-a-c=b`.

Explanation:

Consider the provided formula.

`2S=a+b+c`

We need to solve the formula for b.

Subtract both sides by a.

`2S-a=a-a+b+c`

`2S-a=b+c`

Subtract both sides by c.

`2S-a-c=b+c-c`

`2S-a-c=b`

Hence, the value of the formula for b is
`2S-a-c=b`.
