One side of a parallelogram is twice as long as the adjacent side if the perimeter of the parallelogram is 48 m what is the lenght of the longer side?

Oh, dude, let's break it down. So, a parallelogram has opposite sides that are equal in length. If one side is twice as long as the other, we can call the shorter side x and the longer side 2x. The perimeter is the sum of all sides, which in this case is 2x + 2(2x) + 2x + 2(2x) = 48. Solve that bad boy, and you'll find the longer side is 16 meters.
