A rhombus has a perimeter of . Give the side length of the rhombus.
Like any polygon, the perimeter of the rhombus is the total distance around the outside, which can be found by adding together the length of each side. In the case of a rhombus, all four sides have the same length, i.e.
where is the length of each side.
