The lines going up and down would be parallel and the lines going sideways that you would put your feet on to climb up would be perpendicular

If the perimeter of a rectangle is 140 meters and the length is 5 meters less than 4 times the width, then what are the dimensio

ValentinkaMS [17]

Length (L): 4w - 5

width (w): w

Perimeter (P) = 2L + 2w

140 = 2(4w - 5) + 2(w)

140 = 8w - 10 + 2w

140 = 10w - 10

150 = 10w

15 = w

Length (L): 4w - 5 = 4(15) - 5 = 60 - 5 = 55

Answer: width= 15meters, length=55 meters
