12 m above the ground in the wall. Determine the length of the ladder.

Answer 1

Answer:

We have,

Let the length of ladder=x m

Now, distance between foot of ladder and wall=5m

Height of the window from to ground=12m

∴ By using the hypotenuse theorem

∴x

x=

144+25

x=

169

x=13

Length of the ladder is 3m

Hence, this is answer.
