How do I solve this problem?
Two rectangular rooms each have an area of 240 square metres. If the length of one of the rooms is x metres and the other room is four metres longer, write down the width of each room in terms of x. If the widths of the rooms differ by 3 metres, form an equation in x and show hat this reduces to x^2+4x-320=0. Solve this equation and hence find the difference between the perimeters of the rooms.
