As shown in the figure, the side length of square ABCD is 4, which is the midpoint of BC side, f is the point on DC side, and DF = 14dc, AE and BF intersect at G point. Find the area of △ ABG

As shown in the figure, GM ⊥ AB is made at point m through point G, let GM = x, because Tan α = & nbsp; BEAB = gmam = 24, so am = 2x, and Tan β = bccf = gmbm = 43, so BM = 3x4, am + BM = AB = 4, that is, 2x + 3x4 = 4, the solution is x = 1611. So s △ ABG = 12 × ab × GM = 12 × 4 × 1611 = 3211
