A ladder is placed against a wall such that its foot is at the distance of 2.5 m from the wall and top reaches a window 6 m above the ground. Find the length of the ladder.?

Question

Answer

Hi!

__________________________________

Let AB be the ladder and CA be the wall with the window at A

BC = 2.5 m

CA = 6 m

From Pythagoras theorem , We Have

AB²= BC²+CA²

(2.5)²+(6)²

=42.25

So , AB = 6.5

Thus , the length of the ladder is 6.5 m
