A ladder resting on the wall is grounded 3 metres away from the base of the wall. If the length of the ladder is 5m, what is the height at which it is resting on the wall? Correct Answer <span lang="EN-IN" style=" line-height: 107%; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">4 m</span>

Given:

A ladder resting on the wall is grounded 3 metres away from the base of the wall. If the length of the ladder is 5 m

Calculation:

Height can be calculated by using Pythagoras theorem

⇒ Height = (52 - 32)1 / 2

⇒ Height = 4 m

∴ Required height = 4 m
