How to Find the Perimeter of a Parallelogram

Finding the perimeter of a parallelogram is a very useful skill. Most rooms are parallelograms. A container may be the shape of a parallelogram. Finding the perimeter of a parallelogram is also important to understanding geometry. Here are the steps to finding the perimeter of a parallelogram.

Difficulty: Moderately Easy

Instructions

1. 
    

   Start with a parallelogram. A parallelogram may be a square, a rectangle or a rhombus. In a parallelogram, the sides of the four-sided shape must have two sets of parallel lines. Each side is also equal in length to the opposite side.

2. 
    

   Determine the width and height of the parallelogram. Since the sides are equal, you only need to know the length of one side and either the top or bottom. In mathematics, these measurements are provided. In real life, you may have to measure two sides of a room, container or other item.

3. 
    

   Write down the formula for the perimeter of a rectangle. It is P = 2( W + H), meaning Perimeter = width + height x 2.

4. 
    

   Plug the width and height of the parallelogram into the equation. In this case, the equation would read P = 2(10 + 6)

5. Calculate the equation by adding the width and height and multiplying by 2. This gives you the perimeter of the parallelogram. Perimeter = 2 x 16 = 32. The perimeter of the parallelogram equals 32.
