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 = 3x-5

    so now we know the width is x
    and the length is 3x-5

    "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 + 3x-5 + 3x-5 = 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
