How far should a ladder extend past a roof ledge?

  1. 2 feet

  2. 3 feet

  3. 4 feet

  4. 5 feet

The correct answer is: 3 feet

A ladder should extend 3 feet past the roof ledge. This is considered the ideal length because it allows for proper stability and prevents the ladder from sliding outwards. Option A (2 feet) is likely too short and may not provide enough support, while options C (4 feet) and D (5 feet) may be excessive and make the ladder more prone to wobbling or tipping over. It is important to follow ladder safety guidelines and select the appropriate length for the ladder in order to ensure safety while working at heights.
