Answer:
90 degrees
Step-by-step explanation:
360/4=90
 
        
             
        
        
        
1 foot = 12 inches
Therefore:
2 feet = 24 inches
------------------
2 feet x 725 = 1450 feet
------------------
The real tower is 725 times taller than the actual model.
Ratio:
725 : 1
        
                    
             
        
        
        
To find the area of all of the figures, all you need to do is base x height or the length x width.
Your answers for 1-6 are all correct.
For 7-9, remember that the area is the length times the width. 
7) length x width, 42 x 30=1260 
8) 17 x 22= 374
9) Since the length and width are the same in a square just multiply the side by itself. 2.7 x 2.7= 7.29
Hope this helps.
