2x 5 The area of the rectangle shown is given by the function A()- 2 -5x lfthe width of the rectangle is 13, then the area is 42
PIT_PIT [208]
If you let x = 13:
     Then, Area = 2(13)^2 - 5(13)
                        = 338 - 65
                        = 273 sq ft

If you let 2x-5 = 13:
                  2x = 18
                    x = 6
 
     Then, Area = 2(6)^2 - 5(6)
                        = 72 - 30
                        = 42 sq ft

Therefore, your options are A or C. Your answer can be chosen based on what you assume the width to be. Good luck!
