To find the values for <em>x </em>so that the perimeter of the rectangle is not greater than <em>60 cm</em>, includes <em>25 cm </em>on <em>one side</em>, we have already found the first half of this answer.
The <em>only </em>way to make this <u><</u> 60 is to have the parallel sides (depending on which side is 25,) is <em>5 cm.</em> That way, it will be exactly <em>60 cm</em>, meaning we have reached our goal of <u><</u> 60 cm.
The equation: let x represent the unknown number 5+y3=x*05 (or x divided by 2) y represents the tripled number and x represents the end result. Hope this helps!
