Question

the formula p = 2l + 2w means that the perimeter of a rectangle is equal to twice the sum of its length and its width. solve p = 2l + 2w for w. a. w = (p - 2)/l b. w = (p - 2l)/2 c. w = p - 2 - l d. w = (p + 2l)/2

Explanation:

Step1: Isolate the term with w

Start with $P = 2l+2w$. Subtract $2l$ from both sides of the equation to get $P - 2l=2w$.

Step2: Solve for w

Divide both sides of the equation $P - 2l = 2w$ by 2. We have $w=\frac{P - 2l}{2}$.

Answer:

B. $w=\frac{P - 2l}{2}$
