Question 1196075
Make a few changes:


=====
The length of the garden is 20 feet. The perimeter of the garden must be at least
80 feet and no more than 120 feet.
=====


You obviously would be interested in solving for the width.




w, the width

{{{80<=2*20+2w<=120}}}

{{{40<=20+w<=60}}}

{{{highlight(20<=w<=40)}}}
