The perimeter fencing at a property in western NSW has been impacted by recent flooding events. In April 2022, before any flooding, there was 195 km of fencing. 65% of this fencing was damaged by flooding in June 2022. Unfortunately, before any of the fencing could be repaired, another flood occurred in December 2022 and destroyed 15% of the fencing that remained. What is the percentage change in undamaged fencing at the property between April 2022 (prior to flooding) and December 2022 (after flooding events)?
