Answer:
This is just the application of Pythagoras theorem
To find how high up the wall the ladder reach
⇒ 13^2 = x^2 + 5^2
therefore x^2 = 13^2 - 5^2
x^2 = 169 -25
x^2 = 144
x = 12
therefore the ladder is 12 foot high up the wall

So, plug in our values:
d = 55 *4
And, d = 220
I can't see the answer choices, but I hope this will help you!! Let me know if you have ANY questions.
