Question 114670: The length of a rectangular playing field is 5 feet less than twice its width. If the perimeter of the playing field is 230 feet, find the length and width of the field. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! The length of a rectangular playing field is 5 feet less than twice its width. If the perimeter of the playing field is 230 feet, find the length and width of the field.
------------
Let the width be "x" ft.
Then length = "2x-5" ft.
--------------------
Perimeter = 2(length + width)
230 = 2(3x-5)
115 = 3x-5
3x = 120
x = 40 ft (this is the width)
2x-5 = 75 ft ( this is the length)
