Is the following shape 2D or 3D?

2D stands for two-dimensional. It’s a flat surface with two measurements, like a length and a width. 3D stands for three-dimensional. It’s what we have here on Earth, real life. So there will be three measurements: a length, a width, and then a height.

So is the following shape 2D or 3D? Well, here we have a green flat rectangle, so it’ll be 2D. And not only is it flat, there will only be two measurements: length and width. So once again, this shape would be 2D.
