<p>Here it is, it is probably easy for you guys, but I got stumped (I feel so embarrassed asking such dumb questions):</p>

<p>One side of a triangle has lenght 6 and a second side length 7. Which of the following could be the area of this triangle?</p>

<p>I. 13
II. 21
III. 24
its says the answer is I and II only, but I have no idea as to how to get it. I guest 21 is due to (6*7)/2=21, but I have no idea as to 13.</p>
