Consider this, area for triangle is BH/2.
the two bigger triangles have the same B & H, the three small triangles have the same base and height. thus we can say the three smaller triangles or the 2 larger are equal. with (1) or (2) we can see the area of the full rectangle is 96.
(18*3)*2 or (24*2)*2
