Answer:
Let's denote the length of Ladder B as x. Since Ladder A is 4 feet longer than Ladder B, the length of Ladder A is x + 4.
Now, if Ladder A is cut down to be the same length as Ladder B, it means we are cutting 4 feet off Ladder A. After the cut, the length of Ladder A will be x (the same as Ladder B).
So, after the cut, both ladders will have the same length, and the statement that is true is:
"The length of Ladder A is equal to the length of Ladder B."
