I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
PLEASE SEE ATTACHED IMAGE.
For this case the area is given by:
A = (22 + x) * (28 + x) = 722
Rewriting we have:
616 + 22x + 28x + x ^ 2 = 722
x ^ 2 + 50x + 616 - 722 = 0
x ^ 2 + 50x - 106 = 0
Solving the polynomial we have:
x1 = 2.04
x2 = -52.04
We take the positive root:
x = 2.04 inches:
Answer:
The width of the border to the nearest inch is:
x = 2inches

However, we can find the plot that represents the data.
To draw a scatterplot, we just need to draw points, where the indepedent variable is going to be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, that is the position of each player.
So, all points we need to draw the plot are:
(1, 28)
(2, 13)
(3, 4)
(4, 8)
(5, 15)
(6, 10)
(7, 22)
(8, 7)
(9, 11)
(10, 15)
The image attached shows the plot that represents this data set.
