Question

Avi saw his father placing ladder against a wall 16 ft high , at a distance of 12 ft away from the wall. Help him to find the length of ladder ?​

Answer 1

le the triangle be ∆abc

now

by Pythagoras theorum

a²+b²=c²

16²+12²=c²

(16-12)(16+12)= c²

28×4=c²

112=c²

√112 =c

Answer 2

Answer:

The length of the ladder is 20ft.

Step-by-step explanation:

Given that,

Avi saw his father placing ladder against a wall 16ft high , at a distance of 12ft away from the wall.

The height of the wall is $h=16ft$ and

The distance of the foot of ladder from wall is $d=12ft$

Let the length of the ladder be $l$ we shall find it using the Pythagorean theorem.

According to Pythagorean theorem the length of the ladder is given by the relation

$l^{2}=h^{2}+d^{2}$

Substituting the given values in above relation we get

$l^{2}=16^2+12^2=400\\= > l=20ft$

Therefore,

The length of the ladder is 20ft.
