Answer:
Since each of the four sides of a rhombus has an equal length, the perimeter of a rhombus may be calculated using the formula, Perimeter = 4a, where 'a' denotes the length of the side of a rhombus.
Explanation:
The perimeter of a rhombus is calculated by multiplying one of its four equal sides by four 4. Four times the length of one the sides is applied to determine the perimeter of a rhombus.
