The error in Bryon's reasoning is that he calculated the area of the rectangle instead of the area of the square. To find the area of a square, you just 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
Therefore, the correct area of the square is 42 1/4 square centimeters, not 22 square centimeters.
The square is 6 1/2 cm. and 4 1/2 cm. Bryon calculated the area of the rectangle as 22 square centimeters. What is the error in his reasoning and what is the correct answer?
