Question

The height of wall is 4m and a ladder is placed at a distance 3m.
find the length of ladder used.
(Use Pythagoras Theorem)


pls answer in Pythagoras Theorem​

Answer 1

Answer:

Length of the ladder is 5m.

Step-by-step explanation:

Height of the wall= 4m

Distance between the wall and the base of the ladder=3m

Let the length of the ladder be equal to the hypotenuse of a right angle triangle,

According to Pythagoras Theorem,

Hypotenuse² = Length² + Breadth²

= 4m²+3m²

= 16m²+9m²

= 25m²

Hypotenuse = square root (25)

Hypotenuse = 5m.

Therefore length of the ladder is 5m.

Answer 2

Answer:

5

Step-by-step explanation:

Pythagoras theorem is : (h)2 =(Base)2+ (height)2

and here ladder is placed in distance of 3 m , so the base is 3‌m , and height of wall is 4 m , so height of the triangle formed is 4 m , so , length of the ladder will be hypotenuse of the triangle formed.

So. , (hypo)2 = (3)2 + (4)2

=9+16 =25 ,

so hypotenuse = √25= 5 , so the length of the ladder used = 5 m . thanks ☺️
