Answer:
2.5
Step-by-step explanation:
 
        
                    
             
        
        
        
6 and 2/3 that is the answer
        
                    
             
        
        
        
First we need to find the length. So we do 126/3 to get 42. The length is 42. Now to find perimeter we do 2(42)+2(3) or 42+42+3+3.
Both ways are right ways. The perimeter is 90 meters.
Hope that helps!!
 
        
             
        
        
        
Turn the information into coordinate points.
Point = (time, population)
Point 1 = (1985, 45000)
Point 2 = (2004 , 26000)
Find the slope between these points using the formula
( Slope)—> m = (y2 - y1) / (x2 - x1)
26000-45000/2004-1985=-19000/19= -1000
Average rate of change is decrease of 1000 sea lion per year 
I hope that helped
