approach the problem by splitting it into triangles. use the apothem as the height.

anonymous · Answer

Area = 1/2 * (perimeter) * (apothem) 
 Area = 1/2 * (6 * sides) * (apothem)

anonymous · Answer

well if you have the formulas then just plug and chug lol...
1/2*(12*6)*12

anonymous · Answer

1/2*(12*6)*9 = 324? which is B ! thanks @sylbot
