Question

1. p = 2b + 2h for b

Explanation:

Step1: Subtract \(2h\) from both sides

\(P - 2h = 2b + 2h - 2h\)
Simplifying the right side gives \(P - 2h = 2b\)

Step2: Divide both sides by 2

\(\frac{P - 2h}{2}=b\)
We can also rewrite this as \(b=\frac{P - 2h}{2}\) or \(b=\frac{P}{2}-h\)

Answer:

\(b=\frac{P - 2h}{2}\) (or \(b=\frac{P}{2}-h\))
