Surely it would be easier to just do square root of 49/4 + 49 and add them to get square root 61.25. This therefore equals 7 square root 5 divided by 2 which is the same answer??

I'm using the distance formula, I'm confused where the square root of 1+4 came from. Can someone help?
I assume you know how you get to 449+49 at which point you know you can factor a 49 out of the expression under the square roots so you get 49(41+1) and then you can also factor out a quarter which gets you 49⋅41⋅(1+4) and then it's just the matter of splitting it into two square roots, one of which square roots nicely into a fraction.
