Hey there!! 
Let's take the length of the bigger piece as x inches 
Then, the length of the smaller piece would be x - 8 inches
The sum of these lengths would be 54 inches 
... x + x - 8 = 54 
... 2x - 8 = 54 
... Add 8 on both sides 
... 2x = 62 
... Divide 2 on both sides 
... x = 31 
Hence, the length of the bigger piece = 31 inches 
The length of the smaller piece would be = 31 - 8 = 23 inches 
Hope my answer helps!!
