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.
To rewrite the formula for the perimeter of a rectangle in terms of the width w, we need to isolate w on one side of the equation.
p = 2(l + w)
First, we'll distribute the 2 to both terms inside the parentheses:
p = 2l + 2w
Next, we'll subtract 2l from both sides to isolate the term with w:
p - 2l = 2w
Finally, we'll divide both sides by 2 to solve for w:
w = (p - 2l)/2
Therefore, the formula for the perimeter of a rectangle in terms of the width w is:
w = (p - 2l)/2
