Hi, not sure whether this is Pre-uni or uni mathematics but any help would be greatly appreciated. The question states:
"The canteen in the Davis Road building occupies a total floor space of 12000m2. It is to be redeveloped into three separate areas. Area 1 will be self service. Its length will be twice its width. Area 2 will be table service. Its width will be 2m more than the width of Area 1 but its length will be half the length of Area 1. Area 3 will be academic staff only. Its width will be 1m more than the width of Area 2 and its length will be 1m more than the length of Area 1. Set up an appropriate quadratic equation, and use to calculate the width and length of Area 1, Area 2 and Area 3. Show all steps in your calculation clearly."
Could anyone please help me with an explanantion of how to go about completing this question? I don't even know where to start...
