Will medal. I understand problem 1. Can someone explain the GOT IT problem 1? I don't understand why there's an advantage?

Answer 1

bacause when you use just a single variable like b and apply the formula it goes like this
m= (a/2,b/2)
OM =\[\sqrt{a^2/4 + b^2/4}\]
and then it goes on simply. There's no problem in doing so but it just becomes complicated and increases chances of doing an error.
