Question 787320
<font face="Times New Roman" size="+2">


One more time...from the very top.


Let *[tex \Large x] be <b><i>the measure of a side</i></b> of one of the cut out squares.


Then the length of the bottom will be *[tex \Large 16\ -\ 2x] because there is a square cut out on each end.  Likewise the width of the bottom after the folding is done will be  *[tex \Large 12\ -\ 2x]


So if you want the length of the bottom to be three times the width:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 16\ -\ 2x\ =\ 3(12\ -\ 2x)]


Solve for *[tex \Large x] which is the side dimension of the squares and sufficient to uniquely identify the size of the squares.
