A gardener is planning to plant a rectangular vegetable garden during the spring. The rectangle below represents a plan for the garden with a width of x feet. Find the length of the rectangle if the area of a rectangle is x^2 +12x. (hint: factor the trinomial x^2 +12x +0 using the guess and check method.)

    Recall that Area of a rectangle is \(\large\rm A=\ell\cdot w\)
