no
Explanation:
The area of a square is calculated by multiplying the length of one side by the length of the other side.
So, a 3 cm by 3 cm square has an area of 3 cm * 3 cm = 9 square centimeters.
Therefore, Joe's drawing of a 3 cm by 3 cm square is not a valid shape that has an area of 3 square centimeters and is not right.
