# 3 Rectangles + 1 Triangle = ?

Geometry Level 5

Triangle $ABC$ has integer side lengths. Rectangles $BCDE, ACFG, ABHJ$ are constructed so that $CD = AC + AB$, $CF = AB + BC$, and $BH = (AC + BC)^2$. If $[ABHJ] = [BCDE] + [ACFG]$, how many different values can $[ABC]$ have?

Details and assumptions

$[PQRS]$ refers to the area of figure $PQRS$.
