To calculate the perimeter of a rhombus, 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 rhombus:

1. Measure the length of one of the sides of the rhombus.
2. Write down the length of the side.
3. Multiply the length of the side by 4.
4. The result is the perimeter of the rhombus.

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

Perimeter = 4 × Side

Where Side is the length of the side of the rhombus.

Here’s an example to illustrate the process:

Suppose you have a rhombus with a side length of 8 meters.

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

1. Measure the length of one of the sides: 8 meters.
2. Write down the length of the side: 8 meters.
3. Multiply the length of the side by 4: 8 × 4 = 32 meters.
4. The perimeter of the rhombus is 32 meters.
