Given:
The equation for the area of the first option is:
Where x is the side length of the current square park.
To find:
The side length of the current square park.
Solution:
We have,
It can be written as:
Splitting the middle term, we get
We know that the side length of a park cannot be negative. So, the only possible value of x is 320.
Therefore, the most direct method to solve the given equation is splitting the middle term and the side length of the current square park is 320 meters.
