Answer:
3159.853 km
Step-by-step explanation:
The question says a square has an area of 9,984,670 km^2, which means that all sides are the same length. So you can use the equation:
9984670 = (x)(x) which rearranges to 998470 = x^2
get the square root and you get:
x = 3159.853 km
Sometimes, because if you have a negative number than the opposite is positive and more. Then if you have a positive number it will be negative and therefore less.
