The area of the fence is 6*25=150 square feet.
It will take him 150 / 2 = 75 of 10-minute intervals. 75 min *10 = 750 min = 750/60 hours = 12.5 hours.
50 x 4 = 200
200 -50 = 150

No question is asked so I'm not sure what you are looking for but below I calculated the point where the two equations intersect:
y - x = 4 → y = x + 4
y = - x² + 6x
x + 4 = - x² + 6x
x² - 5x + 4 = 0
(x - 4)(x - 1) = 0
x = 4, x = 1
when x = 4, then y = x + 4 = 4 + 4 = 8 → (4,8)
when x = 1, then y = x + 4 = 1 + 4 = 5 → (1,5)
The line and parabola intersect at two points: (4,8) and (1,5)
3.50 x 3 = 10.50
6.85 x 2 = 13.70
10.50 + 13.70 = 24.20
