That's Correct!
It's Wrong!
The formula 2 × (L+W) is used to calculate the perimeter of a rectangle. The perimeter of a rectangle is the sum of all its sides, which is calculated by adding twice the length (L) and twice the width (W) of the rectangle. Therefore, the correct answer is the perimeter of a rectangle.
