Hello!
When finding the perimeter of a rectangle, you have to consider the properties of a rectangle. A rectangle has two pairs of equal sides where one is the width, while the other one is the length. 
Now looking back at your question, it says "... a rectangle that is x units wide" ⇒ you let the width = x ; this is the same with "y units long" ⇒ length = y. Perimeter can just be : P = 24.  
Therefore,
The equation would be:
x + x + y + y = P. 
2x + 2y = P. 
(Sub in P = 24)
∴ 2x + 2y = 24. (This should be your answer.)
:) Good luck (Message me if you have any problem)
        
             
        
        
        
First, let's create the ratios of sweetened to unsweetened. To do this, you would have to subtract the number of people that preferred unsweetened from the total.
Westside mall: 15:30 or 

Eastside mall: 13:26 or 

Now, you would divide to both ratios.
15 ÷ 30 = 0.5
13 ÷ 26 = 0.5 
They have the same sum, meaning, 
they are the same. 
Westside Mall shoppers are just as likely to prefer unsweetened tea as Eastside Mall shoppers. I hope this helps!
