Answer:C. 0.038 km² > 3.8 m² > 380 cm² > 3800 mm²  Step-by-step explanation:Convert every measurement to the same unit, say, square metres. (a) 3.8 m² No conversion necessary (b) 380 cm² [tex]\text{Area} = \text{380 cm}^{2} \times \left (\dfrac{\text{1 m}}{\text{100 cm}} \right )^{2} = \textbf{0.038 m}^{2}[/tex] (c) 0.038 km² [tex]\text{Area} = \text{0.038 km}^{2} \times \left (\dfrac{\text{1000 m}}{\text{1 km}} \right )^{2} = \textbf{38 000 m}^{2}[/tex] (d) 3800 mm² [tex]\text{Area} = \text{3800 mm}^{2} \times \left (\dfrac{\text{1 m}}{\text{1000 mm}} \right )^{2} = \textbf{0.0038 m}^{2}[/tex]In decreasing order, 0.038 km² > 3.8 m² > 380 cm² > 3800 mm²
