Since the room is square, we know that all four sides will be the same length. To find the length of one side of the room, we just need to take the square root of 169. In doing so, we get a final answer of 13.
Answer:
2nd option
Step-by-step explanation:

If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 100 , then 100² = 10000
60² + 80² = 3600 + 6400 = 10000
then
60² + 80² = 100²
thus the triangle is right
