Answer: 7 feet
Step-by-step explanation:
Since all 4 sides of a square are equal, you do 28 / 4 = 7 feet, which is the answer.
 
        
                    
             
        
        
        
The answer is 3x^2 + 19x - 12.
        
             
        
        
        
X is 7 and y is 2 I am pretty sure
