Question

The base of a ladder is 6 metres from a wall. The height of the wall is 7 metres.
What is the minimum height the ladder must be to reach the top of the wall? (give your
answer to 3 significant figures)​

Answer 1

Answer:

Here's the calculation to determine the height of a step ladder: If your ceiling is 12 feet in height, subtract the four feet needed for the worker to reach the work area, and the remainder would be the height of the step ladder needed, in this case, a 8 foot step ladder.
