# Perimeter of rectangle calculator

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

- Measure the length of one of the shorter sides of the rectangle.
- Write down the length of the shorter side.
- Measure the length of the longer side of the rectangle.
- Write down the length of the longer side.
- Multiply the length of the shorter side by 2.
- Multiply the length of the longer side by 2.
- Add the results of steps 5 and 6.
- The result is the perimeter of the rectangle.

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

**Perimeter = 2 × (Length + Width)**

Where Length is the length of the rectangle and Width is its width.

Here’s an example to illustrate the process:

Suppose you have a rectangle with a length of 10 meters and a width of 5 meters.

**To find the perimeter of this rectangle, you would follow these steps:**

- Measure the length of one of the shorter sides: 5 meters.
- Write down the length of the shorter side: 5 meters.
- Measure the length of the longer side: 10 meters.
- Write down the length of the longer side: 10 meters.
- Multiply the length of the shorter side by 2: 5 × 2 = 10 meters.
- Multiply the length of the longer side by 2: 10 × 2 = 20 meters.
- Add the results of steps 5 and 6: 10 + 20 = 30 meters.
- The perimeter of the rectangle is 30 meters.
