Question

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?

Answer 1

the answer is exactly 15.125

Answer 2

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
