Area for square is $\ ?^2$

So (x - 3)^2 = (x - 3)(x - 3)

Umm, you know how a square has all the same sides, right? ^_^

lol yeah

So because you're given a square tile,y you can apply the rule x^2 :>

Your given side is (x - 3), because it's a square ~ it'll have the same sides in all four sides.

See? So now apply (x - 3)^2

Note that something^2 is something$\ \times$ itself.

Like 2^2 = 2 * 2 = 4
