(no, i did not peek) Same solution as Albert in post #6 I started out by joining the midpoints of the original square hoping to simplify the problem: all triangles. Returning to the matter after an hour or so I noticed de sum of the heights of a pair of opposite triangles being the same as for the other pair. ha + hc = hb + hx Bases of the triangles being the same and the red surfaces also the same... SX + SB = SA + SC SX = SA + SC - SB = 28 Delightfully simple. (Lucky day!) |
