A

Assuming that

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
