Question 834756
"Suppose that the length of a certain rectangle is 3 meters less than four times its width" ----> L = 4W - 3


" The perimeter of the rectangle is 24 meters" ----> P = 24


-----------------------------------------------------------------------------


P = 2L + 2W


24 = 2(4W-3) + 2W


24 = 8W-6 + 2W


24 = 10W-6


24+6 = 10W


30 = 10W


10W = 30


W = 30/10


W = 3


L = 4W - 3


L = 4*3 - 3


L = 9



So the length is 9 meters and the width is 3 meters.
