The length of a rectangle is three times its width. if the perimeter is at most 112 centimeters, what is the greatest possible value for the width?

14cm
Since the length of the rectangle is 3 widths long, it can also be represented by 3 widths. So the perimeter would be 8 widths long.( 2lengths+2widths)
Hence, 112cm=8widths
             Width=112cm/8
                      =14cm
Thus, the greatest possible value for the width is 14cm

It creates dogx^2 and then flip your answer and multiply by 2
