Answer 2

To add the areas in square centimeters (cm²) and square millimeters (mm²), you first need to ensure that the units are the same. You can convert square millimeters to square centimeters since 1 cm² = 100 mm².

Now, let's convert 7 mm² to square centimeters:

1 cm² = 100 mm²

So, 7 mm² = 7/100 cm² = 0.07 cm²

Now that both areas are in the same unit (cm²), you can add them:

2 cm² + 0.07 cm² = 2.07 cm²

So, the sum of 2 square centimeters and 7 square millimeters is 2.07 square centimeters.
