Question

A ladder is placed in such a way that its foot is at a distance of 4 metres
from a wall and its top reaches a window 3 metres above the
ground
Foot of the ladder is pushed in the same straight line towards the wall
so that its distance from the wall is 3m. How far above the ground, the
top of ladder touches the wall ? ITS A 25 MARKS QUESTION AND I WILL MARK AS A BRAINLIST IF YOU WRITE THERE MARK ME AS A ​

Answer 1

Answer:

We have,

Let the length of ladder=x m

Now, distance between foot of ladder and wall=5m

Height of the window from to ground=12m

∴ By using the hypotenuse theorem

∴x

2

=(12)

2

+(5)

2

x=

144+25

x=

169

x=13

Length of the ladder is 3m

Hence, this is answer.
