Answer :
w = width
l= length
w = l/2 - 4
l/2 repreaents half the length
- 4 is 4 less than half the length
l= length
w = l/2 - 4
l/2 repreaents half the length
- 4 is 4 less than half the length
[tex]the \ width : \ w \\ \\ the \ length : \ l \\ \\ If \ the \ width \ is \ 4 \ inches \ less \ than \ \frac{1}{2} \ the \ length, \\\\ that\ gives \ the \ equation: \\ \\ w = \frac{1}{2} \ l - 4[/tex]
