The area for a triangle is calculated 1/2(b*h)
so b*h is 15*3
Which equals 45
So you take 1/2 of that, 45*1/2, or 45/2 is
22.5

Answer: SECOND OPTION.
Step-by-step explanation:
By definition a polygon with twelve sides is called "Dodecagon".
The sum of the interio angles of a polygon of 12 sides is 1800 degrees.
Therefore, the measure of each angle of a this type of polygon is:
1800°/12=150°
Then, keeping the information above on mind, you can conclude that the correct answer is the second option, which is: 1800°
