The error in Byron's reasoning is that he calculated the area of a rectangle instead of a square. To find the area of a square, you need to multiply the length of one side by itself.

The correct answer is:
(6 1/2 cm) x (6 1/2 cm) = 42 1/4 square centimeters

So, the correct area of the square is 42 1/4 square centimeters, not 22 square centimeters.
thats not a choice.
I apologize for the oversight. Let me correct my response:

The correct answer is:
(6 1/2 cm) x (6 1/2 cm) = 42.25 square centimeters

So, the correct area of the square is 42.25 square centimeters, not 22 square centimeters as calculated by Byron.
