How to Solve the Perimeter Formula for the Width of a Rectangle?

The perimeter p of a rectangle can be expressed using the formula: p = 2w + 2l. In this formula, w represents the width and l represents the length of the rectangle. To solve the formula for the width w, we need to isolate w on one side of the equation.

Here are the steps to do this:

1. Start with the perimeter formula: p = 2w + 2l.
2. Subtract 2l from both sides to isolate the term with w: p – 2l = 2w.
3. Now, divide both sides by 2 to solve for w: w = (p – 2l) / 2.

So, the width w of the rectangle can be expressed in terms of the perimeter p and the length l by the formula: w = (p – 2l) / 2.
