The exact answer is 12 root 2, but you can also say approximately 17.
I got this by finding the square root of 369, and then 81. After finding these values, you get the equation...
a^2 + 9^2 = 369
a^2 + 81 = 369
a^2 = 288
And then I just found the square root of 288
I would say 640.5 centimeters. However, remember that this is high school work, and I am only in middle school. This may not be correct, as I am doubting myself, yet cannot find errors in my work. Please take caution with this answer! Hope this isn't a detriment to you, bye! :)
