Hi Lynn, the question can be done with the following steps :


Middle portion of Rod Y
= 158cm - Rod X - Rod Z
= 158cm - 48cm - 62cm
= 48cm

Now we know that the length of Rod Y is equal to the middle portion + the right overlap + the left overlap.


So left overlap

= Length of Rod Y - middle portion - right overlap

= 69cm - 48cm - 9cm
= 12cm
