Astronomers determine that a certain square region in interstellar space has an area of approximately 2.4 / times 10^72.4*10 7 (light-years) 2, where a light-year is a unit of astronomical distance. Assuming that this region is a square, then a single side of the square would be approximately how many light-years long?

1.5 * 10³⁶ light-years

Explanation:

A certain square region in interstellar space has an area of approximately 2.4 * 10⁷² (light-years) ². The area of a square can be calculated using the following expression.

A = l²

where,

A is the area of the square

l is the side of the square

l = √A = √2.4 * 10⁷² (light-years) ² = 1.5 * 10³⁶ light-years
