Let 
be the dimensions of the rectangle. We know the equations for both area and perimeter:
So, we have the following system:
From the second equation, we can deduce
Plug this in the first equation to get
Refactor as
And solve with the usual quadratic formula to get
Both solutions are feasible, because they're both positive.
If we chose the positive solution, we have
If we choose the negative solution, we have
So, we're just swapping the role of 
and 
. The two dimensions of the rectangle are 
and 
Answer:
The weight of box and pocking material 
pound
Step-by-step explanation:
Let the weight of box and packing material 
weight of package 
pounds
total weight 
pound
Subtract both side by 
Hence weight of box and packing material pound
