Step-by-step explanation:
A picture can explain a lot. The coordinates are shown in the attachment.
Positive angles are measured counterclockwise (CCW). Negative angles are measured clockwise. So, -3π/4 is the same as +5π/4, since a circle is 2π = 8π/4.

Solution.
L = 4w --------<span>The length of a rectangle is four times its width.
</span>2w + 2L ≤ 130 ------- <span>the perimeter is at most 130 centimeters.
</span>Now, if substitute the first equation into the second inequality you will get
2w + 2 • (4w) ≤ 130.
Therefore, the inequality model in C is correct.
Bonus.
If you solve the inequality you will have a final answer w ≤ 13. The greatest value being 13.
Hope it helps,
