Well, the area is length * width, so if it's 42, I guess the answer would be 20+1. 21*2=42
-------edit-------
I was on my phone and didn't see all of it. I don't think this logic works anymore, it's already solved so... yea...

A = l * w, so 42 = (x) (x + 1) is the equation you have to solve

x(x+1)=42. x^2+x-42=0. It's quadratic, so factor it and set each factor equal to zero.
