## 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:

1. Measure the length of the first side of the parallelogram.
2. Measure the length of the second side of the parallelogram.
3. 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.
4. If the parallelogram does not have adjacent sides of equal length, then repeat steps 1 and 2 for the remaining two sides.
5. Add up the lengths of all four sides of the parallelogram.
6. 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.
