Given :
Trey is putting up fence around a 750 foot by 540 foot lot.
To Find :
How many feet of fence does he need.
Solution :
Perimeter is given by :
[tex]P=2(L+B)[/tex]
Putting value of L and B above , we get :
[tex]P=2\times ( 750+540)\ foot\\\\P=2580\ foot[/tex]
Therefore, 2580 foot of fence is required.
Hence, this is the required solution.
