Parallelogram perimeter calculator

Perimeter is the distance around a two-dimensional shape.

Parallelogram — is a quadrangle in which the opposite sides are pairwise parallel, that is, they lie on parallel lines. Particular cases of a parallelogram are a rectangle, a square, and a rhombus.

A parallelogram is a four-sided polygon with opposite sides parallel to each other. To calculate the perimeter of a parallelogram, you need to add the lengths of all four sides or twice the sum of its two sides (length and width). The formula for finding the perimeter of a parallelogram is:

P = 2(a + b)

where P is the perimeter and a and b are the lengths of the two adjacent sides.

How to Use the Parallelogram Perimeter Calculator

Our parallelogram perimeter calculator makes it easy to find the perimeter of your parallelogram. Simply follow these steps:

1. Enter the length of one of the adjacent sides (a) in the first box.
2. Enter the length of the other adjacent side (b) in the second box.
3. Our calculator will automatically calculate the perimeter of your parallelogram.

Here's an example:

Example: In the parallelogram above, we have adjacent sides a = 8 cm and b = 10 cm. So the perimeter P will be:

P = 2(8 + 10) = 36 cm

Parallelogram Perimeter Examples

Here are some examples of finding the perimeter of a parallelogram using the formula:

Example 1: Find the perimeter of a parallelogram with adjacent sides of length 6 cm and 9 cm.

P = 2(6 + 9) = 30 cm

Example 2: Find the perimeter of a parallelogram with adjacent sides of length 4.5 cm and 7 cm.

P = 2(4.5 + 7) = 23 cm
