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?

**Reiny**, Wednesday, June 9, 2010 at 8:04amThe 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=760

x=95

y=95(3)=285

w=95

L=285
