Answer:
its 4 bv 1x4 is 4 4x4 is 16 and 16x4 is 64! goodluck!
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.
Multiply 88 by 7, then multiply 88 by 3 and move the decimal point one to the left. Then add those two numbers. That's your answer.
