Answer:
A = 54.8 - (1200/x) - 2x
Step-by-step explanation:
Given <em>x</em> the wide and <em>y</em> the height, we have
x*y = 50
⇒  y = 50/x
The area of the printed region is A = w*h
where 
Wide: w = (x-2*1.2) = x-2.4
Height: h= (y-2*1) = y-2
then
A = (x-2.4)(y-2) = xy - 2.4y - 2x + 4.8 = 50 - 24*(50/x) - 2x + 4.8
⇒  A = 54.8 - (1200/x) - 2x
 
        
             
        
        
        
In mathematics, a percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100.
        
             
        
        
        
Well since there is 12 months in a year you would multiply 35 by 12, so the answer is 420
