Hundreth? 1.64, you round up after 5.
        
             
        
        
        
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!
