5900f4a31000cf542c50ffb6 | 5 | Problem 311: Biclinic Integral Quadrilaterals | 301967 |
Description
For example, the following quadrilateral is a biclinic integral quadrilateral: AB = 19, BC = 29, CD = 37, AD = 43, BD = 48 and AO = CO = 23.
Let B(N) be the number of distinct biclinic integral quadrilaterals ABCD that satisfy AB2+BC2+CD2+AD2 ≤ N. We can verify that B(10 000) = 49 and B(1 000 000) = 38239.
Find B(10 000 000 000).
