Step 1
<u>First situation</u>
when a ladder is leaning against a wall
Let
x-------> the distance of the bottom of the ladder from the wall
L-------> the length of the ladder
<u>Find the length of the ladder</u>
Applying the Pythagorean Theorem
 ------> equation
 ------> equation 
Step 2
<u>Second situation</u>
when the ladder will be lying flat on the ground
<u>Find the length of the ladder</u>
In this situation the length of the ladder is equal to

square both sides
 ------> equation
 ------> equation 
Step 3
equate equation  and equation
 and equation 

therefore
<u>the answer is</u>
 the length of the ladder is
