Minimum possible area o B 4
Maximum possible area of B 28(4/9) or 28.44

Since the triangles are similar, sides are in same proportion.

Case (1) Minimum possible area
#8/8=a/3 or a=3# Sides are 1:1
Areas will be square of the sides ratio #=1^2=1#
#:. Area Delta B = 4#

Case (2) Maximum possible area
#8/3=a/8 or a=64/3# Sides are 8:3
Areas will be #(8/3)^2=64/9#
#:. Area Delta B =(64/9)*4=256/9=28(4/9)#
