The answer is true to all of them.
If the problem youre solving as the value of the x and y you can make those linear equations, however u can make them with only the x val
X=3
x is the width of the sidewalk
The outside dimensions of the walkway are 12 + 2x by 8 + 2x
The total area is (12 + 2x)(8 + 2x)
The total area minus the area of the pool should be equal to the area of the pool
Hoped this helped!
Luckly i still have my notes and the answer was about 3.1%. I hope this helped.
