Hey so the answer would be B
        
                    
             
        
        
        
So, first, what are the two sides? 
let's call then x and y
we know that 2(x+y)=12.5 (that's the distance around)
so that means that x+y=6.25 (I just divided both by 2)
now, x=4y (from "4 times as long as it is wide")
so we can substitute: 
x+4x=6.25
5x=6.25
x=1.25
so one side, is 1.25 and the other will be 1.25*4=5
and for the area we multiply the two: 
1.25*5=6.25 square kilometers, and this is the answer!
        
                    
             
        
        
        
Answer:
(7,5)
Step-by-step explanation:
{2x + 4y = 34
{4y = 27 - x
2x + 27 - x = 34
x=7 
4y = 27 - 7
y = 5 so the answer is ( 7,5)
 
        
                    
             
        
        
        
Answer:
38 km
Step-by-step explanation:
1. The formula to find the area of a trapezoid is  , where a and b are the bases and h is the height.
, where a and b are the bases and h is the height.
2. To find the area, all we have to do is plug in these values and simplify!
3. (Solving)
Therefore, the area is 38 km.
