Question

5) A ladder is placed in a slanting position against a wall such that it touches it, 20 m above the ground. The foot of the ladder is 15 m away from the bottom of the building. What is the length of the ladder?​

Answer 1

Answer:

We can use Pythagoras Theorem here though it is Physics...

So one of the side is 20m

and the other one is 15m

the other one is the hypotenuse of the triangle, as this forms a triangle if you draw it...

Let Hypotenuse be H.

According to Pythagoras Theorem:

$H^2=20^2+15^2\\=400+225\\=625$

$H=sqrt. of 625\\\\H= 25m$

Therefore, Height of the ladder is 25m...

I hope you understood...

Explanation:

Answer 2

Answer:

use Pythagoras theorem

first side = 20 m

other side=15 m

Let the hypotenuse be p

According to Pythagoras theorem

p² =s²+n²

p²=20²+15²

p²=400+225²

p²=625

sqrroot of 625

p²=25
