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

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
