Creating EqUation apes, let's see if we can come up he same method you ve used In e. You'll need to use: Now that we've done the work to nd the area of the three previous sh with a general equation for the area of these types of shapes. So usung t the last 3 problems see if you can put all of the equations together Into on ~An equation for the area of a triangle -An equation for the height of the triangle -The Sin Law or Cos Law for the side length of one of the triangle -And finally an equation to add up the areas of all of the triangles This equation should include \"n", number of sides of the polygon, and "l', the length of each side
