Which formula represents the perimeter of a rectangle?

Length X Width
2 (Length + Width)
Length + Width
2 (Length + Height)

The correct answer is: 2 (Length + Width)

The perimeter of a rectangle is the total distance around the edges of the rectangle. To calculate it, you add together the lengths of all four sides. Since a rectangle has two lengths and two widths, the formula for the perimeter can be expressed as the sum of the lengths of the opposite sides: Perimeter = Length + Length + Width + Width, which simplifies to Perimeter = 2 * (Length + Width). This formula effectively captures the requirement to account for both pairs of opposite sides in the calculation. Thus, using 2 multiplied by the sum of the length and the width provides a streamlined way to express the total perimeter. The other options do not accurately reflect the relationship needed to find the perimeter of a rectangle. For instance, multiplying length by width gives the area, while only adding the length and width does not account for both pairs of sides. The reference to height in another option is also irrelevant when discussing the perimeter of a rectangle, which does not typically involve height.
