1 dollar = 1 cent

If $1 = 100 cents

then $1 = 10c x 10c

substitute for 10c = 1/10 of a dollar

so $1 = (1/10 of a dollar) x (1/10 of a dollar)

so $1 = 1/100 of a dollar .. which is 1 cent.

One square meter is ten decimeter times ten decimeter. Because a square meter is an area while one decimeter is not.

One dollar is not 10 cents times ten cents. Because a dollar is not an area. There is no way a dollar can be $^2.

No, it's not picky.
