Answer:

"Answer are:


A false (w is 11)  


B false (it won't be a rectangle if there is no width - it'll be a line - but the equation would not work)  


C True (must be a positive number)  


D True (you put the value of l in to find w)  


E True (you deduct the lengths from 62 to find w)  


The value of w cannot be a negative number.  


Substitution is used to replace the variable l with a value of 20.  


2L + 2W = 62  


L + W = 31  


W = 31-L  


W = 31-20 = 11
