Two factors that give a product of 1600 can be 80 × 20
        
             
        
        
        
Answer:
<A = <B 
=> 8x - 8 = 5x + 25
<=> 3x = 33
<=> x = 11
with x = 11 => mB = 5.11 + 25 = 55 + 25 = 80⁰
 
        
                    
             
        
        
        
11 * 11 * 6 = 726 square inches
