Answer:

6 miles

Explanation:

2A = 72

A = 72/2

A = 36

Area = s²

36 = s²

s = 6 miles

Answer:

6 miles

Explanation:

Let's say the length of the sides of the square is x.

The area of a square is denoted by: A = x².

Here, we're given that twice the area of the square is 72, so we can write this is 2 times the area, which is 2 * x². Set this equal to 72 and solve:

2x² = 72

x² = 36

x = 6

Thus the answer is 6 miles.
