1. Point B is in the middle of AC because nothing like that is mentioned.
2. Figure is NOT drwan to scale
St1: If we know all sides then we can find the area. Even if B is not in the middle of AC, height of the triangle will remain the same.
Height of box = 128/16 = 8
Base of triangle = 4
Height of triangle = √80 = 4√5
Area = 8√5 : SUFF
St2: We don't know all the dimensions of the triangle. Other dimentions could be (4,8), (2,16) or (1,32): INSUFF
