Question 53777
The length of a rectangular playing field is 5 ft. less than twice its width. If the perimeter of the playing field is 230 ft., I nned to find the length and width of the field. 
--------------
Let the width be "x" ft.
Then the length is "2x-5"
Perimeter = 2(length+width)
230 = 2(2x-5+x)
230=2(3x-10)
115=3x-10
3x=125
x=41 2/3 ft (This is the width)
2x-5= 78 1/3 ft (This is the length)
Cheers,
