There is a Math website that has a lot of Calculus story problems. He shows you how to solve problems.

also on Youtube;
Patrickjmt channel. The Yourmathgal channel is also good,
both have over 800
videos. Have gone to
both since 2011.
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
I think the answer is the first one f(2) = g(2) and f(0) = g(0)
2x + 12 = 20
2x = 32
32/2x
X= 16
