You solved not for the width of the strip but for twice the width of the strip. You stated: "The space between that figure and the 14 x 15 figure is x." but if it is the case that x is the rugless border, then the problem to be solved is:<br />(14-2x)(15-2x)=110<br />thus<br />210-58x+4x**2=110<br />4x**2-58x-100=0<br />x**2-(29/2)x-25=0<br />(x-2)(x-25/2)=0<br />so x=2 is the realistic answer if x is the rugless border.<br /><br />The arithmetic works nicer your way, but in that case you have to say you are going to make x TWICE THE RUGLESS BORDER.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6078192846661822178.post-44164926270599452182012-04-16T16:48:04.141-07:002012-04-16T16:48:04.141-07:00Didn't you skip a step?
