Answer:
Width = 8 feet
Step-by-step explanation:
To solve this equation easily, we can plot the equation provided in a graphing calculator, and fin the points where y = 0
y = -5/8*(x-2)(x-10)
With those points, we subtract the values of x and find the solution of your problem.
Please see the attached graph
Width = x2 - x1
x2 = 10
x1 = 2
Width = 8 feet
