Answer:
no change in area
Step-by-step explanation:
The original area is 
A = 12*5 = 60 ft^2
The new length and width
l = 12 + .25 (12) = 12+3 =15
w = 5 - .2 (5) =5-1 = 4
The new area is
A = l*w =15*4 = 60 ft^2
The area is the same
 
        
             
        
        
        
You have to do 3.14 times the diameter of the circle.
        
                    
             
        
        
        
 5 km  =  5000 M =  500000 Cm
 
        
             
        
        
        
The answer is 12cm because area (420) divided bye height (35) gives you the corresponding side 12cm.
