If I understand correctly the diameter will also be the longest diagonal across the square.

From Pythagoras you know that where a is the side length.

(nb: because side length must be greater than 0 I have discarded the negative root)

Now what do you know about the area of a square? - Feb 15th 2011, 01:28 AMmido22
