Answer:
9m
Step-by-step explanation:
Consider length of ladder as hypotenuse and height of window from ground as height of right angles triangle.
Let distance of foot of ladder from wall be x
Using pythagoras theorem,
15²=12²+x²
=>225=144+x²
=>x²=225-144=81
=>x=9m
9m will be right answer for this question
