Janabel has a piece of paper such that one side is red and the other side is blue.
She cuts a triangle of area 126 out of the paper and labels its vertices A, B, and
C. With the red side facing her, she folds point A over some line parallel to
BC. It turns out that the total blue area she can see is twice the area of the
total red area she can see! Find the total red area she can see.
