The perimeter of a rectangle is the sum of its sides, which are two widths and two lengths:
Since the length is twice the width, we have , and the formula for the perimeter becomes
So, we have
we have
----> inequality 1
The solution of the inequality 1 is the shaded area below the solid red line
The solution is the region D and region C
-----> inequality 2
The solution of the inequality 2 is the shaded area above the solid blue line
The solution is the region B and region C
The solution of the system is the common area
so
The solution is the region C
see the attached figure
therefore
the answer is the option C
Region C
