2 mm
2 mm
7 mm
2 mm
5 mm
square millimeters

Explanation:

Step1: Calculate area of full rectangle

$$16 \times 9 = 144 \text{ mm}^2$$

Step2: Calculate area of first cutout

$$7 \times 2 = 14 \text{ mm}^2$$

Step3: Calculate area of second cutout

$$4 \times 2 = 8 \text{ mm}^2$$

Step4: Subtract cutouts from full area

$$144 - 14 - 8 = 122 \text{ mm}^2$$

Answer:

122 square millimeters
