Let x be the length, y be the width and p be the perimeter.
p = 2x + 2y
Since the length is 3 times the width
x = 3y
So,
2400 = 2(3y) + 2y
2400 = 6y + 2y
2400 = 8y
y = 300
Now plug y back in,
x = 3(300)
x = 900
The length is 900 ft and the width is 300 ft

What you must do in this case is to find the roots of the polynomial.
 We have then:
 x ^ 2 + 20x + 100 = 36
 Rewriting:
 x ^ 2 + 20x + 64 = 0
 The values of the roots are:
 x1 = -4
 x2 = -16
 Remember that the values of the roots are what make the polinome zero
 Answer:
 x1 = -4
 x2 = -16
