## Perimeter of parallelogram calculator

To calculate the perimeter of a parallelogram, you need to add up the lengths of all four sides. Here’s how you can use a calculator to find the perimeter of a parallelogram:

- Measure the length of the first side of the parallelogram.
- Measure the length of the second side of the parallelogram.
- If the parallelogram has two adjacent sides of equal length, then multiply the length of one of these sides by 2 to get the total length of these two sides.
- If the parallelogram does not have adjacent sides of equal length, then repeat steps 1 and 2 for the remaining two sides.
- Add up the lengths of all four sides of the parallelogram.
- The result is the perimeter of the parallelogram.

**Alternatively, you can use the following formula to calculate the perimeter of a parallelogram:**

P = 2(a + b)

**where:**

- P is the perimeter of the parallelogram
- a is the length of one of the parallel sides of the parallelogram
- b is the length of the adjacent side of the parallelogram

Using this formula, you can easily calculate the perimeter of a parallelogram if you know the lengths of its sides.
