A ladder used for access extends 2 feet above the landing, and the problem requires 3 feet. How much more extension is needed?
Correct Answer
B) 1 foot.
The added extension needed is 3 feet minus 2 feet, which equals 1 foot.
Why This Is the Correct Answer
The added extension needed is 3 feet minus 2 feet, which equals 1 foot.
Why the Other Options Are Wrong
Option A: 1 inch.
1 inch. is not aligned with the supported result for ladder safety; it has the wrong label or classification even if the number looks close.
Option C: 2 feet.
2 feet. is above the supported result for ladder safety; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 3 feet.
3 feet. is above the supported result for ladder safety; it likely double-counts allowance, uses the wrong unit, or rounds too early.
