Question: What rectangle is this talking about?

The rectangle: $$\{(x,y)\mid 0 \leq x \leq 2 , 0 \leq y \leq 1 \}$$

How does this convey a rectangle?

Please help me out. Thank you.

Answer: 
The one with corners at (0,0), (2,0), (0,1), and (2,1).
It's this rectangle:

Notice that the corners are at $(0,0)$, $(0,1)$, $(2,0)$, and $(2,1)$. The rectangle is just all of the points $(x,y)$ such that $0\le x\le 2$ and $0\le y\le 1$.
