You are not "only given the area...", you are also given that is 7 more than . You also know that the area is given by , so substitute: And with the given value for area: Put it in standard form: Solve the quadratic (it factors, 22 and 15 have a difference of 7, hmmm), discard the negative root. The positive root is and is 7 more than that.
