Maximum area of triangle = #85.3333#
Minimum area of triangle = #41.7959#

Explanation:

#Delta s A and B # are similar.

To get the maximum area of #Delta B#, side 16 of #Delta B# should correspond to side 6 of #Delta A#.

Sides are in the ratio 16 : 6
Hence the areas will be in the ratio of #16^2 : 6^2 = 256 : 36#

Maximum Area of triangle #B =( 12 * 256) / 36= 85.3333#

Similarly to get the minimum area, side 7 of #Delta A # will correspond to side 16 of #Delta B#.
Sides are in the ratio # 16 : 7# and areas #256 : 49#

Minimum area of #Delta B = (8*256)/49= 41.7959#
