Question 596545: The length of a regular pool is 6 meters less than twice its width. If the pool's perimeter is 126 meters, what are its dimensions?
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Let x = width of the pool
2x-6 = length of the pool
2W + 2L = Perimeter
2(x) + 2(2x-6) = 126
2x + 4x - 12 = 126
6x - 12 = 126
6x=138
x=138/6
x=23 meters WIDTH
2x-6=46-6=40 meters LENGTH
Chcck: 2*23 + 2*40=46 + 80 = 126 It checks!!!
