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).
In your final answers, include all of your calculations.
Part A. To rewrite the formula for the perimeter of a rectangle in terms of the width w, we need to isolate w in the equation p = 2(l + w). Follow these steps:
1. Divide both sides of the equation by 2: p/2 = l + w
2. Subtract l from both sides of the equation: p/2 - l = w
So, the final formula in terms of the width w is: w = p/2 - l
Part B. In order to isolate the variable w in the equation p = 2(l + w), I first divided both sides of the equation by 2. This resulted in the equation p/2 = l + w. Following this, I subtracted l from both sides of the equation in order to isolate w completely. The final formula that I derived was w = p/2 - l.
