# Not the squares you were looking for

• A $$5\times5$$ square has area $$\pi$$.
• A $$7\times7$$ square has area $$8$$.
• An $$8\times8$$ square has area $$0$$.
• A $$10\times10$$ square has area $$30$$ (not quite $$13$$).

Why?

The answer should be clear when you find it, and does not involve arbitrary or tenuous connections.
