"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.
