Answer 2

The length of the ladder is 4 meters.

Step-by-step explanation:

Height of the ladder from the ground, h = 3.2 m

The distance from the wall, d = 2.4 m

It is required to find the length of the ladder. Let L be the length of the ladder. It can be calculated using Pythagoras theorem as :

$L^2=h^2+d^2\\\\L^2=(3.2)^2+(2.4)^2\\\\L=4\ m$

So, the length of the ladder is 4 meters.
