Answer
Rectangle or Square
Why
Only square and rectangle has the property of having a 2 90 degrees angle or right angle.
 
        
             
        
        
        
Find the slope of the line connecting (1990,435000) and (2005,482300):
        482300-435000        47300
m = ----------------------- = ---------------- = 3153/yr (approx)
          2005 - 1990                15 yr
Use the point-slope formula to find the equation of this str. line:
y-435000 = (3153/yr)(x-1990)
The year 2020 is 30 years after 1990.  Thus, the expected pop in 2020 is
given by     y-435000 = 3153(30) = 94590, so that y = 529590.
