Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. the perimeter of a rectangle is given by the formula $p = 2w + 2l$, where $w$ is the width and $l$ is the length. rearrange the formula for the length ($l$). $\bigcirc$ $l = p - \frac{1}{2}w$ $\bigcirc$ $l = 2p - 2w$ $\bigcirc$ $l = \frac{1}{2}p - w$ $\bigcirc$ $l = \frac{1}{2}w - p$

Explanation:

Step1: Start with the formula

We have the perimeter formula \( P = 2w + 2l \). Our goal is to solve for \( l \).

Step2: Subtract \( 2w \) from both sides

Subtract \( 2w \) from each side of the equation: \( P - 2w = 2l \). This isolates the term with \( l \) on the right - hand side.

Step3: Divide both sides by 2

Divide each side of the equation \( P - 2w = 2l \) by 2. Using the distributive property of division over subtraction, we get \( \frac{P}{2}-\frac{2w}{2}=l \), which simplifies to \( l=\frac{1}{2}P - w \).

Answer:

\( l=\frac{1}{2}P - w \) (corresponding to the option \( l=\frac{1}{2}P - w \))
