Arhombus with side length s is shown below. the perimeter, p, of a rhombus is proportional to the length of each side, s. which equation represents this relationship?

Oh nevermind, the best display for the proportions of the rhombus is .
This is because a rhombus has 4 equal sides, like a square. So, in order to find the perimeter, we multiply one side by 4!
Alternatively, 
Hope this helps
