Question 840582: The width of a rectangular swimming pool is 24 meters less than the length, and the perimeter is 108 meters. Find its dimensions. Answer by thejackal(72) (Show Source):
You can put this solution on YOUR website! P = perimeter = 108; P is found by the equation P = 2w + 2l, where w is width and l is length
since w = l - 24
then P = 2w + 2l can be written as P = 2(l-24) + 2l
thus 108 = 2l - 48 + 2l
108 + 48 = 4l
156/4 = l = length = 39
i'll leave you to work out the width
