The complete sentence is presented as follows;

The area of the land is 2.31 × 10¹⁰ square meters in scientific notation

We can represent this area as 2.31 × 10⁴ square kilometers

Explanation:

The question relates to Laws of indices specifically in powers of 10

The given parameters of the dimensions of the rectangular section of forest land are;

5.5 × 10⁵ meters by 4.2 × 10⁴ meters

Therefore, the area, "A" the rectangular section of forest land is A = 5.5 × 10⁵ m × 4.2 × 10⁴ m = 2.31 × 10¹⁰ m²

1 km² = 1 × 10⁶ m²

∴ 2.31 × 10¹⁰ m² = 2.31 × 10¹⁰/(1 × 10⁶) km² = 2.31 × 10¹⁰ ⁻ ⁶ km² = 2.31 × 10⁴ km²

2.31 × 10¹⁰ m² = 2.31 × 10⁴ km²

Therefore, the complete sentence, can be written as follows;

The area of the land is 2.31 × 10¹⁰ square meters in scientific notation

We can represent this area as 2.31 × 10⁴ square kilometers.
