The perimeter of a parallelogram is the sum of the lengths of all four sides. It can be calculated by adding together the length of the top side, the length of the bottom side, and twice the length of one of the sides.

The perimeter of a parallelogram is used in various real-world applications, such as calculating the amount of fencing needed to enclose a parallelogram-shaped garden or field. It is also used in calculating the perimeter of buildings or rooms with parallelogram-shaped floor plans.

The formula for determining the perimeter of a parallelogram is defined as:

\(where\)

\(AB\) \(=\) \(DC \text{ and } AD\) \(=\) \(BC\)

\(P\): the perimeter of the parallelogram

\(AB\): the length of side AB

\(BC\): the length of line BC

The SI unit of perimeter is: \(meter\text{ }(m)\)

## Find \(P\)
