Answer:
0.33 ft
Step-by-step explanation:
From the diagram, triangle ACE is similar to triangle BCD.
Therefore,


Let the Length of the Ladder, L
Using Pythagoras theorem




To find the least value, we have to equate the derivative of L to 0.

Therefore:
b³-1080=0
b³=1080
b=10.26
The minimum length of the ladder is:

=0.33 ft
