Length + width = half of perimeter, so you need more information...

Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
If you do not know the length and width of ALL sides, then as far as I know it isn't possible to find the perimeter unless you measure each side and then find it.
It not possible you nit witt that is not true length x width = area If you know length and area, solve width width = area / length then 2 x length + 2 x width = perimeter
It isn't clear how you would define the "perimeter" for a 3D figure. The base is the product of length x width.
Divide the perimeter by 2 and subtract the length to get the width. Multiply the length by the width to get the area. P=2L+2W P-2L=2W (P/2)-L=W A=LW
