Your Challenge: The Leaning Ladder!

Imagine a sturdy ladder leaning against a tall wall. We know two crucial pieces of information:

  • The ladder reaches 40 meters up the wall.
  • The base of the ladder is 15 meters away from the bottom of the wall.

Your mission, should you choose to accept it, is to determine the total length of this ladder. What do you think? Is it 40m, 50m, or something in between? Take a moment, grab a pen and paper if you like, and try to visualize the shape it forms.

Hint: Think Triangles!

If you’re scratching your head, here’s a little nudge in the right direction: when a ladder leans against a wall on flat ground, it creates a very special shape. That’s right, a right-angled triangle! And whenever you have a right-angled triangle and you know the lengths of two sides, there’s a famous mathematical theorem that can help you find the third side: the Pythagorean Theorem.

This theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle – which is our ladder!) is equal to the sum of the squares of the other two sides (the wall height and the distance from the wall).

The Formula:

a² + b² = c²

Where ‘a’ and ‘b’ are the lengths of the two shorter sides (legs), and ‘c’ is the length of the hypotenuse (our ladder).

🚨 Spoiler Alert: The Solution Revealed! 🚨

Ready for the big reveal? Let’s walk through the steps to find the ladder’s length together!

Step 1: Identify Your Sides

  • Side ‘a’ (height up the wall) = 40 meters
  • Side ‘b’ (distance from the wall) = 15 meters
  • Side ‘c’ (the ladder’s length) = Unknown!

Step 2: Apply the Pythagorean Theorem

Using our formula, a² + b² = c²:

  • Length² = 40² + 15²
  • Length² = 1600 + 225
  • Length² = 1825

Step 3: Calculate the Length

Now, to find the actual length, we need to find the square root of 1825:

  • Length = √1825
  • Length ≈ 42.72 meters

When we round this to the nearest whole meter, the ladder is approximately 43 meters long.

So, the correct answer is A (43 m)!
