Is the ladder suspended in space?
Do you have a question?
a ladder 20m long rests against a vertical wall so that the foot of the ladder is 1m from the ground
2 answers
an unusual position -- the ladder is not on the ground.
I expect you mean the foot of the ladder is one meter from the wall. I assume you want the height of the top of the ladder. If the height up the wall is h, then
1^2 + h^2 = 20^2
