Problem Statement

Let N14N_{14} be the answer to problem 14.
Rectangle ABCDABCD has area 2N14\sqrt{2N_{14}}. Points EE, FF, GG, and HH lie on the rays AB\overrightarrow{AB}, BC\overrightarrow{BC}, CD\overrightarrow{CD}, and DA\overrightarrow{DA}, respectively, such that EFGHEFGH is a rectangle with area 22N142\sqrt{2N_{14}} that contains all of ABCDABCD in its interior. If tanAEH=tanBFE=tanCGF=tanDHG=148, \tan\angle AEH = \tan\angle BFE = \tan\angle CGF = \tan\angle DHG = \sqrt{\frac{1}{48}}, then EG=mnpEG=\tfrac{m\sqrt{n}}{p}, where mm, nn, and pp are positive integers, mm and pp are relatively prime, and nn is not divisible by the square of any prime. Compute m+n+pm + n + p.
