That's not just some random formula, it's the pythagorean theorem. Start thinking about points on a coordinate plane as really being triangles.

because if you think, you can just about do it in your head the distance between 3 and 4 is 7 the distance between 6 and 5 is 11 so you have a right triangle, one side is 7, the other sides is 11 and the hypotenuse (distance) is \[\sqrt{7^2+11^2}\]

Exactly. Plus, if you understand the concept, you can use that to help you learn new things or solve problems similar, which just knowing the formula can't help you with.
