Question 141916
Let x= width of the rectangular field
x+2 = length of the field.


Area = Width * Length
120 = x(x+2)
120 = x^2 +2x


This is a quadratic equation so set it equal to zero:
0=x^2 + 2x - 120


Let's hope it factors:
0=(x-10)(x+12)

x=10 or x=-12


Reject the x=-12, since you can't have a negative width.

x=10 yds = Width
x+2= 12 yds = Length
