Let width be =x
Then length is x+1
Area of rectangle= x(x+1)=x²+1    The polynomial
so from the question we have
                     x²+x=25
              ⇒    x²+x-25=0 This is a quadratic equation
And solving for x
        We have x={ -1+_√(1²-4*1(-25)}/2
                        = {-1+-√101)/2= -5.524 or 4.524
Neglecting negative no. we have width=4.524 feet
