Imagine you are an advisor for a sitting US president. You have just received word that three small boats appear to have attacke
d a US port. The president wants to retaliate, but you think more evidence is needed before US forces attack. What historical event could you reference to support your case best?
The Gulf of Tonkin incident was the event that led to the United States engaging more directly in the Vietnam War. The confrontation involved North Vietnam and the United States in the Gulf of Tonkin. Originally, the United States had reported two attacks, and blamed them on North Vietnam. However, over time, there was a widespread belief that at least one, if not two of the attacks were false. This could be repeated in the case of the example if not enough information is gathered before retaliating.
The answer is D. 12 cm, because in order to find the area of a parallelogram you need the formula A = (b)(h), which is base times height. So 20cm x 12cm equals 240cm^2 :)
