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.
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?
