Perimeter of Rhombus
To calculate the perimeter of a rhombus we need to know a side length. A rhombus is a shape with four equal sides. The formula to calculate the perimeter of a rhombus is same like the formula of a square. The perimeter means the sum of all side lengths. For example a length of a fence around a rhombic garden. The elementary unit is one metre (1 m).
