Let's substitute values on so we have just one variable.

First recognize that we can replace $$6km$$ with $$(2k)(3m)$$ to get:
QUANTITY A: $$n^2$$
QUANTITY B: $$(2k)(3m)$$

Now replace $$2k$$ with $$n$$, and replace $$3m$$ with $$n$$ to get:
QUANTITY A: $$n^2$$
QUANTITY B: $$(n)(n)$$

Cheers,
Brent
