2 Dimensions

Welcome to the flatland! The second dimension is the only other dimension that the human race can truly create and relate to. Objects in flatland have width, and height. Your shadow or your reflection in a mirror, for example, could be considered 2 Dimensional objects. In fact, I'm quite sure this is a world you witness every day...especially if you're a Mario Brothers fan.

A = S2

Area = Length x Width

These are the typical formulas used to find the "Area" of a square or rectangle.

An example of an ancient Egyptian painting. Ancient art was usually 2 Dimentional-looking because, at the time, artists did not have a 3 Dimensional perception. Egyptian carvings, for example.
