The perimeter of a parallelogram, as for any polygon, is the sum of the lengths of its sides. The opposite sides of a parallelogram are parallel and have the same measurement. The formula for its perimeter is twice the sum of the base and the height or "2(b + h)."

The height of the parallelogram is the length of its vertical side, which is denoted by the variable “h” or “s.” The base is the span of its horizontal side, which is commonly represented by “b” or “w.”

A parallelogram with a base of 6 units and a height of 2.5 units has a perimeter of 17 units.
