Question

A ladder is placed in such a way that its foot is at a distance of 5 metre from the wall and it's tip reaches a window 12 metre about the ground. Determine the length of the ladder
​

Answer 1

Answer: is 13

Step-by-step explanation:

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

hope it helps

Correct question:

A ladder is placed in such a way that its foot is at a distance of 5 metre from a wall and its top reaches at window 12 metre above the ground determine the length of the ladder.

Given:

Distance between foot of ladder and wall = $\tt{5m}$

Height of the window from to ground = $\tt{12m}$

Length of the ladder = x

All the things together form a right angled triangle, as given in image.

∴We will solve by using Pythagoras theoram.

Solution:

➞$\tt{x^2}$ = $\tt{5^2}$+$\tt{12^2}$

➞$\tt{x^2}$ = $\tt\sqrt{144+25}$

➞$\tt{x^2}$ = $\tt\sqrt{169}$

➞$\tt{x}$ = $\tt{13}$

Length of the ladder is 13m.
