To find the real length and width of the bag, we need to convert the measurements from centimeters to inches.
From the scaled x-ray image, we can see that the bag is approximately 6 centimeters long and 4 centimeters wide.
Using the scale 1 centimeter = 2 inches:
Length of the bag = 6 centimeters x 2 inches/centimeter = 12 inches
Width of the bag = 4 centimeters x 2 inches/centimeter = 8 inches
Therefore, the correct option is:
D. The length of the bag is 12 inches, and the width of the bag is 8 inches.
