Step-by-step explanation:
The graph of 
is shown in the image.
The vertical axis represents the values of t
The horizontal axis represents the pH values as a function of t.
We want to know when the pH value is 0 and when it is equal to 1. then we look in the graph for the cut point of the graph with the horizontal axis. For that value the pH will be 0.
In the graph, note that when .
Then we look in the graph for the point in the curve for which 
Note that this point is

The formula for perimeter is P = 2L + 2W. We are told that the perimeter is 8 times the width, so P = 8w. We are also told that the length is 90. So our revised formula is 8w = 2(90)+2w, which simplifies to 8w = 180 + 2w, and 6w = 180. That means that w = 30. And there you go!
