Problem Statement
Let N14 be the answer to problem 14. Rectangle ABCD has area 2N14. Points E, F, G, and H lie on the rays AB, BC, CD, and DA, respectively, such that EFGH is a rectangle with area 22N14 that contains all of ABCD in its interior. If
tan∠AEH=tan∠BFE=tan∠CGF=tan∠DHG=481,
then EG=pmn, where m, n, and p are positive integers, m and p are relatively prime, and n is not divisible by the square of any prime. Compute m+n+p.
