1. The problem asks to find the total length in centimeters when given 2 meters and 550 millimeters. 2. We use the conversion formulas: - $1 \text{ meter} = 100 \text{ centimeters}$ - $1 \text{ millimeter} = 0.1 \text{ centimeters}$ 3. Convert 2 meters to centimeters: $$2 \text{ m} = 2 \times 100 = 200 \text{ cm}$$ 4. Convert 550 millimeters to centimeters: $$550 \text{ mm} = 550 \times 0.1 = 55 \text{ cm}$$ 5. Add the two lengths in centimeters: $$200 \text{ cm} + 55 \text{ cm} = 255 \text{ cm}$$ 6. Therefore, the total length is $255$ centimeters.
