What is the minimum length ladder that a worker needs to access a landing nine feet above the adjacent floor

Answers

Answer 1

The minimum length of the ladder needs to be 9 feet.

Answer 2

Answer: A 12 foot ladder would be the minimum length that is going to be required by a worker to access a landing nine feet above the adjacent floor

So with the standard terms the ladder should be at least 1 unit away for 4 feet of height so, keeping in mind the unitary method:

Height Away from base

4 1

9 x

The amount a 9 feet ladder should be away is:

x = 2.5 feet away from the base

Using the Pythagoras Theorem:

a² + b² = c²

place the values for the right triangle (a = 2.5, b = 9):

2.5² + 9² = c²

= 9.34 feet

Now, we know that the length of the ladder should always be more than the height you are trying to reach:

9.34 + 2 = 11.34

The minimum height of the ladder should be 11.34 feet. As a result, rounding off would result in a 12 foot ladder.
