Question 59150: 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, find the length and width of the field. Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! 230=2W+2(W-5)
230=2W+2W-10
230+10=4W
240=4W
W=240/4
W=60
PROOF
230=2*60+2(60-5)
230=120+2*55
230=120+110
230=230
