Question 1161357: A rectangle’s length is 3 yards less than 5 times of its width. If the rectangle’s perimeter must be between 18 and 90 yards, what is the range of its width? Use an inequality to solve this problem. Answer by solver91311(24713) (Show Source):
The perimeter of a rectangle is given by but in this case we know that , so the perimeter of your specific rectangle is represented by:
The correct answer depends on what you mean by "between". If the perimeter must be in the open interval then:
On the other hand, if your definition of between means that the perimeter must be in the closed interval then just replace the operator with the operator
