Answer:
235 × 10⁴ m²
Explanation:
We want to convert;
47mm²•60m² + 5km²•47dm² to m²
Let's get the various conversions;
1 mm² = 10^(-6) m²
1km² = 10^(6) m²
1 dm² = 10^(-2) m²
Thus;
47 mm² = 47 × 10^(-6) m²
Similarly;
5 km² = 5 × 10^(6) m²
Also;
47 dm² = 47 × 10^(-2) m²
Thus our original equation in m² gives;
(47 × 10^(-6) × 60) + (5 × 10^(6) × 47 × 10^(-2)) = 235 × 10⁴ m²
