Question 935516
They say that the area of the rectangle is 36 square inches, and we know that are of a rectangle is l x w 

So we have {{{l*w = 36}}}

Now you just need to think of two numbers that multiply together and give you 36, such as 4 and 9, 12 and 3, 18 and 2, etc

The question only asks for ONE possible value of p, so we just need to choose one set of length and width, in this case I will choose 18 and 2 

{{{p=2*(l*w)}}}
{{{p=2*(18+2)}}}
{{{p=2*20}}}
{{{p=40}}}

So one possible value of p is 40 inches.
