Answer :
Final answer:
The side length s of a square can be found by taking the square root of the area. In this case, the side length of a square with an area of 1.69km² is approximately 1.3km.
Explanation:
To find the side length s of a square with a given area, you would use the formula of the area of a square, which is Area = s².
In this question, we need to find the side length s of the square where the Area = 1.69km². Reversing the formula will give us the length of the side, so the equation would be s = √Area.
Therefore, in this case, s = √1.69km². The answer is s = 1.3km (rounded to one decimal place).
