the length of a rectangle is 25cm twice its width the perimeter of the table must be less than 335 cm.find the maximum dimensions of the table if each dimension is an interger

algebra 
Reiny,
width  x
length  2x
2x + 2(2x) < 335
6x < 335
x < 55.8
but we can't go over 335 and x must be an integer, so
x = 55
width = 55
length = 110
check:
if w=55, l = 110 , Perimeter = 330 < 335
if w = 56, l = 112, Perimeter = 336 > 335 , no good
