Answer 1

A picture is extremely important with this problem!

 

This Forum doesn’t allow nice graphics, but let’s try:

 

*  *  *  *  *  *  *  *  *  *  *  *

*                                            *

*                                            *

*                                            *

*                                            *

*                                            *

*                                            *

*                                            *

*                                            *

*                                            *

*                                            *

*  *  *  *  *  *  *  *  *  *  *  * 

 

Count them carefully.  Then, realize that there are 4 corners;  between the corners on each side are 10 more posts.  That makes a total of 44 posts.

Answer 2

Draw and label a square.

Mark a post at one corner

From that corner to the next corner are 11 posts.

This makes a total of 12 posts.

Do this for the other three corners.

For the four sides he needs 48 posts.
