Answer:
[tex]l=238\ yards[/tex]
Step-by-step explanation:
From the question we are told that:
Area of Rectangle A=6183
Equation of Length
[tex]l=9w-14[/tex]
Where
[tex]w=width\ of\ triangle[/tex]
Generally the equation for Area of Rectangle is mathematically given by
[tex]A=(9w-14)w[/tex]
[tex]A=9w^2-14w[/tex]
[tex]6183=9w^2-14w[/tex]
[tex]9w^2-14w-6183=0[/tex]
[tex]w=28[/tex]
Therefore
[tex]l=9(28)-14[/tex]
[tex]l=238\ yards[/tex]
