There are 7 letters in fission, which we'll use as a factorial in the numerator. Of those 7 letters, there are two I's and two S's. To account for these repeating letters, we'll use the factorials of how many times the letters repeat and plug them into the denominator.
The factorial of 7 should be your numerator, and two factorials of 2 should be your denominator:
There are 1260 different permutations of the word fission.

Answer:
The height of wall where 30-foot ladder reaches is 29.39 foot.
Step-by-step explanation:
Consider a triangle ABC showing AC be the 30 foot ladder that is resting on a wall AB and foot of ladder is 6 foot from the wall that is BC = 6
We have to find the height of wall where ladder is reaching.
Since building and foot of ladder makes a right angle at B.
Let AB be x foot.
PYTHAGORAS THEOREM STATES THAT THE SUM OF SQUARE OF BASE AND PERPENDICULAR IS EQUAL TO THE THE SQUARE OF HYPOTENUSE.
Applying Pythagoras theorem,
Thus, the height of wall where 30-foot ladder reaches is 29.39 foot.
