Answer:
In order to calculate perimeter, you need to add together the lengths of all four sides of the square. You are given the length of one side. Remember, all sides of a square are equal, so really you already have the measures of each side. Then, you add them together, so 6 + 6 + 6 + 6 = 24 inches.
Step-by-step explanation:
 
        
                    
             
        
        
        
The length l is given as:
l = 2 w – 6
where w is the width
 
We know that the fencing is 30 feet therefore the
perimeter (excluding the side of the house) is:
P = l + 2 w = 30
2 w – 6 + 2 w = 30
4 w – 6 = 30
w = 9
 
So the length l is:
l = 2 (9) – 6
l = 12
