Answer:
7 - 2 / x = 4 + 10 / x 
or , 7 - 4 = 10 / x + 2 / x 
or , 3 = 12 / x 
or , x = 12 / 3 
Therefore , x = 4
 
        
                    
             
        
        
        
Let, the width = w
We know, A = 2(lw + wh +hl )
250 = 2(10w + 5w + 50)
250 = 2(15w + 50)
250 = 30w + 100
30w = 250 - 100
w = 150/30
w = 5
In short, Your Answer would be Option C) 5 cm
Hope this helps!
