What is the perimeter of a parallelogram?

2(length + width)
bh
sum of lengths of sides
4a

The correct answer is: sum of lengths of sides

The perimeter of a parallelogram is determined by adding together the lengths of all its sides. In a parallelogram, there are two pairs of opposite sides that are equal in length. Therefore, the formula for finding the perimeter can be summarized as the sum of the lengths of one pair of opposite sides multiplied by two. This can also be expressed as 2 times the sum of the length and width, which relates to the first option. However, the most straightforward definition is indeed the total length when considering all sides. In other options, one presents the area of a parallelogram (bh) which is unrelated to the concept of perimeter. Another indicates a formula specific to squares (4a), which does not apply to parallelograms as it assumes all sides are equal rather than addressing the sides individually. As such, the correct answer emphasizes the fundamental idea of perimeter as a linear measure summing the lengths of the sides.
