width --- x
length ---- x+8
area = x(x+8) = 180
x^2 + 8x - 180 = 0
solve this quadratic using any method you learned.
You must have learned at least one method or else you would not have
been given a problem such as this.
remember that x can only be a positive real number, so you have to
reject any negative value of x you get.
