Before he boards a flight, Martin's bag is scanned at the airport. The figure shows a scaled x-ray image of his bag.
Using the scale 1 centimeter = 2 inches, find the real length and width of the bag.
Based on the scale, the length of the bag on the x-ray image is 3.5 centimeters.
To find the real length of the bag, we will use the fact that 1 centimeter on the x-ray image represents 2 inches in reality. Therefore, the real length of the bag is:
3.5 centimeters x 2 inches/centimeter = 7 inches
Similarly, if the width of the bag on the x-ray image is 2 centimeters, the real width of the bag can be calculated as:
2 centimeters x 2 inches/centimeter = 4 inches
Therefore, the real length of the bag is 7 inches and the real width of the bag is 4 inches.
