dilemma time (math) again
 

pinwheels...I have a square that's 15 1/2 inches I want to put a row of pinwheels on the top and bottom, in my mind and not good at math I would need 5 3 1/2 sqr pinwheels did I figure this out right? thanks for your help that is 5 for top and 5 for bottom

If your square is 15 1/2 inches UNFINISHED, then yes, your math is correct. You would need 5--3 1/2 inch square blocks UNFINISHED for top and 5 for bottom.

thank you thank you..... for once I figured something right:o
