Question

A ladder of 5m length
laid against a wall, the
distance b/w the foot of the
wall and foot of ladder is
3m. find the height at which
the ladder touches the wall?​

Answer 1

Answer:

4 m

Step-by-step explanation:

The ladder and the wall form a triangle.

hypotenuse of triangle is 5m

one side is 3m

other side = ?

by Pythagoras theorem

5^2 = 3^2 × side^2

thus the remaining side is 4m

Answer 2

The height at which the ladder touches the wall is 4 m.

Step-by-step explanation:

Given : A ladder of 5 m length  laid against a wall, the  distance b/w the foot of the  wall and foot of ladder is  3 m.

To find : The height at which  the ladder touches the wall?​

Solution :

Length of ladder= 5 m

Distance of foot and wall = 3 m

We need to calculate the height at which the ladder touches the wall  let 'x'.

Using Pythagorean theorem ,

$x^2=\text{Length of ladder}^2-\text{Distance of foot and wall}^2$

$x^2=5^2-3^2$

$x^2=25-9$

$x^2=16$

$x=4$

Therefore, the height at which the ladder touches the wall is 4 m.
