If possible, show the diagrams on how to do these:

1. Cut a regular heptagon into 20 pieces and rearrange those pieces to create two identical regular seven-pointed stars.
2. Use then same twenty pieces to form four smaller regular heptagons.

OK, JEK:

Take a regular heptagram (7-pointed star), inscribed in a circle, and calculate the area of the small heptagon in the centre ( relative to the radius of the circle).

The formula can be modified for the general case of any odd n-gram (5,7,9...), but there's a slight difference in the formula when it's an even n-gram (like the 6-sided 'star of David').

Nothing very hard about it, but it's a bit of fun related to the puzzle you posted.
