### Technique 1: Fundamental Method
BASIC PERIMETER FORMULA FOR A PARALLELOGRAM
The essential method for the perimeter of a parallelogram is just the sum of all its sides. This technique is probably the most easy and intuitive solution to calculate the perimeter.
- Measure the size of every aspect of the parallelogram.
- Add up the lengths of all the edges to seek out the perimeter.
- For a parallelogram with sides a, b, and c, the perimeter is P = a + b + c + a (or P = 2a + 2b, or P = 2a + b + c).
For instance, as an instance now we have a parallelogram with sides of size 4, 5, 4, and 5. To calculate its perimeter, we merely add up the lengths of every aspect: P = 4 + 5 + 4 + 5 = 18.
P = a + b + c + a or P = 2a + 2b or P = 2a + b + c
