Designing Solar Panels – The space available for the installation of three (3) solar collecting panels requires that their lengths differ by the amounts shown in the illustration below, and that the total of their width be meters. To be equally effective, the area of each panel must measure exactly square meters. (a) For variables , , and , express each variable as a function of . (Hint: Consider the area of each panel separately). [6 mks] (b) Based on part (a) above, write an appropriate equation (in terms of variable ) to represent the sum of variables , , and . [4 mks] (c) Hence, find the dimensions of each panel.
