The diagonals
AC
and
BD
of the convex quadrilateral ABCD with area 28 intersect each other at point O. Two lines are drawn through the midpoints of segments
BO
and
DO
so that they are both parallel to the diagonal
AC
. Find the area of the portion of the quadrilateral that is between those lines.

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
