The formula for the perimeter of a rectangle is p=2(l+w).
Part A. Rewrite the formula for the perimeter of a rectangle in terms of the width w. In your final answer, include all of your work.
Part B. In two or more complete sentences, describe the process you followed while isolating the variable w in the equation p=2(l+w).
explain
Part A:
We want to rewrite the formula p=2(l+w) in terms of the width w. To do this, we follow these steps:
1. First, we'll divide both sides of the equation by 2:
p/2 = l + w
2. Now, we'll isolate w by subtracting l from both sides:
w = p/2 - l
So, our re-written formula in terms of width w is: w = p/2 - l
Part B:
To isolate the variable w in the given equation p=2(l+w), I first divided both sides of the equation by 2 to remove the 2 in front of the parentheses. This gave me p/2 = l + w. Then, I isolated w by subtracting l from both sides of the equation, which resulted in the formula: w = p/2 - l.
