# Perimeter of Rhomboid

To calculate the **perimeter of a rhomboid** we need to know a length of all its sides. A rhomboid has two opposites sides with same length so you can know only the length of its adjacent sides. It is similar like a rectangle. If rhomboidÂ´s adjacent sides are same (it means all sides are same), it is a rhombus. The **perimeter of a rhomboid** is a phrase which means a total sum of all sides length. For example a length of a fence around a rhomboidal garden. The elementary unit is one metre (1 m).

## Perimeter of Rhomboid - formula

**Perimeter of Rhomboid** = 2 × (side length a + side length b)

P = 2 × (a + b), where a ≠ b
