Final answer:
To solve for the length of the rectangle given the perimeter and width, use the formula l = (p - 2w)/2
Step-by-step explanation:
To solve for the length of the rectangle, we rearrange the formula for the perimeter of a rectangle:
p = 2l + 2w
Solving for l, we isolate the l term by moving the 2w term to the other side of the equation:
l = (p - 2w)/2
Therefore, the correct solution for the length of the rectangle is l = (p - 2w)/2 (Option C).
