Geometry

Question Analysis:  
This question involves applying the Pythagorean Theorem to a real-world scenario where a ladder, a wall, and the ground form a right triangle.  
The main focus is on finding the hypotenuse (ladder length) when the two legs (wall height and ground distance) are given.  

Key Concept Explanation:  
The Pythagorean Theorem states:  
 
where is the height of the ladder on the wall, is the distance from the wall, and is the ladder length.  

Step-by-Step Solution:  
1. Identify given values:  
  - Distance from the wall:  
  - Height of ladder on the wall:  
  - Ladder length: (unknown)  
2. Apply the Pythagorean Theorem:
