Option 2. Byron found the perimeter of the rectangle. The correct area is 22 square centimeters.
To find the area of a rectangle, you multiply the length by the width. In this case, Byron mistakenly multiplied the sum of the length and width instead. The correct calculation should be 6 1/2 * 4 1/2 = 29 1/4 square centimeters.
Use the image to answer the question.
An illustration shows a rectangle of length as whole number 6 start fraction 1 over 2 end fraction centimeters and width as whole number 4 start fraction 1 over 2 end fraction centimeters. The lengths are horizontally positioned and widths are vertically positioned.
