The dimensions of the booklet can be found by setting up an equation based on the given information. Let the width be $w$ cm. Then, the length is $2w - 2$ cm. The area of the rectangle is given by the product of its length and width, so $w(2w - 2) = 40$. Solving this quadratic equation, we find that $w = 5$ cm, and the length is $2(5) - 2 = 8$ cm. Therefore, the dimensions of the booklet are 5 cm by 8 cm.
