A rectangular garden has an area of 60 m2. The length of the garden is 4 m more than its breadth. Using this information, answer the following.
(i) If the breadth of the garden is x metres, write an equation in x that represents the given area.
(ii) Factorise the equation obtained in part (i) to find the possible numerical values of x.
(iii) State the dimensions of the garden and show that they give the required area of 60 m2.
