The perimeter of a parallelogram is found by adding up all four sides.
Since there are two pairs of side with equal lengths, two sides must have a length of 
.
So the perimeter would be
or 
.
To find the value of the other side length, you would divide the remaining perimeter not include in the other sides by 
.
So 
.
That means the other side length would be
