Combined area is 5.454 × 10^7 km²
Step-by-step explanation:
- Step 1: Find the combined area of Asia and Europe.
Area of Asia = 44,600,000 km²
Area of Europe = 9,943,106 km²
⇒ Combined Area = 44,600,000 + 9,943,106
= 54,543,106 km²
- Step 2: Convert to one significant figure.
54,543,106 = 5.454 × 10^7 km² (Dividing and multiplying by 10^7)
