\end{figure} The weighted networks in Figure 4 represent two possible Logos.
The weights denote lengths in millimetres.
  1. Calculate the shortest length of stitch required to embroider Logo 1 .
  2. Calculate the shortest length of stitch required to embroider Logo 2.
  3. Hence, determine the difference in the length of stitching required for the two Logos.
