Algebra HELP:(

I am terrible at word problems. How do I work this?
A large park is to be built in the shape of a rectangle. The length is to be 5 m shorter than three times the width. The perimeter of the park is to be 750 m. What will be the length and
width of the park?

The main idea is to "translate" the English into math
let the width be x
"The length is to be 5 m shorter than three times the width."
length = 3x5
so now we know the width is x
and the length is 3x5
"The length is to be 5 m shorter than three times the width."
Isn't perimeter the sum of all the sides ? So ...
x + x + 3x5 + 3x5 = 750
now you have an easy equation to solve, let me know what you got. 
8x+(10)=750
8x=760
x=95
y=95(3)=285
w=95
L=285
