Be nice if we were sure of the question. I will guess that you want the hypotenuse.
c^2 = a^2 + b^2
a = 6 km
b = 6 km
c^2 = 36 + 36
c^2 = 72
c = sqrt(72)
c = sqrt(9 * 8)
c = 3*sqrt(8)
c = 3 * 2.83
c = 8.49
112 over 10,000 because it is point zero-one hundred-twelve ten thousandths
The answer is a² + 6. "Sum of a squared and 6" means you square a value and then add 6 to it.
the answer you are looking for is 5 9/20 pounds
sorry but it as to be twenty character
319049
as 100,042 + 98,117 + 120,890 = 319,049
