Answer:

See Explanation

Explanation:

The question is incomplete, as there are lots of missing details in the question. To do this, I will make assumptions

See attachment for question illustration where


y \to the height of the second floor


x \to the distance where the base of the ladder is placed


l \to the length of the ladder

So, we are to solve for x.

Using Pythagoras theorem, we have:


l^2 = x^2 + y^2

Make
x^2 the subject


x^2 = l^2 - y^2

Take square roots of both sides


x = \sqrt{l^2 - y^2

The above is the expression to calculate the base length of the ladder.

Assume


y=50; l = 30

So, we have:


x = \sqrt{50^2 - 30^2


x = \sqrt{2500 - 900


x = \sqrt{1600


x =40
