Problem Statement:
A 26cm ladder is placed against a wall in such a way that the foot of the ladder is 10cm away from the wall. Determine the distance of the upper end of the ladder from the ground.
Solution:
To solve this problem, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.
Given:
- Length of the ladder (hypotenuse) = 26 cm
- Distance of the foot of the ladder from the wall = 10 cm
We need to find the distance of the upper end of the ladder from the ground.
Step 1: Identify the right-angled triangle
In this problem, the ladder forms the hypotenuse of a right-angled triangle. Let's label the sides of the triangle.
- Hypotenuse (ladder) = 26 cm
- Base (distance of the foot of the ladder from the wall) = 10 cm
- Height (distance of the upper end of the ladder from the ground) = ?
Step 2: Apply the Pythagorean theorem
According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
So, we have:
(Height)^2 + (Base)^2 = (Hypotenuse)^2
(Height)^2 + (10 cm)^2 = (26 cm)^2
(Height)^2 + 100 cm^2 = 676 cm^2
(Height)^2 = 676 cm^2 - 100 cm^2
(Height)^2 = 576 cm^2
Step 3: Find the height
To find the height, we take the square root of both sides of the equation.
Height = √576 cm^2
Height = 24 cm
Step 4: Answer
The distance of the upper end of the ladder from the ground is 24 cm.

The distance of the upper end of the ladder from the ground is 24 cm.
