Question

a ladder of length 2.6m reaches the bottom edge of the window when it is placed at distance of 2.4m from the wall the foot of the ladder moved 1.4m towards wall to touch top of the window find the width of the window
​

Answer 1

Step-by-step explanation:

case 1

We have

H=2.6 m

B=2.4m so, using Pythagoras theorem , we get

p = 1m ( when ladder is touched at edge) .....(1)

case 2

we have

H=2.6 m and B=1.4 m so,

p=✓4.8= 2.19 m....(2)

on subtracting 1 from 2 we get

width of window= 1.19 m
