<PRE><B>Question 498149</B>
Perimeter of a Rectangle = 72 meters
Length  = l=4w+6 
Width  = w
Perimeter of a Rectangle = length + length + width + width
Perimeter of a Rectangle = 2l + 2w
72 = 2(4w+6) + 2w
72 = 8w+12 + 2w
72-12 = 10w
60=10w
60/10=w
w=6
Length  = l=4w+6  (Given)
Length  = l=4(6)+6
Length  = l=24+6=30
Dimensions of the rectagle
Length  = 30m, Width=6m, Perimeter=72m
