Answer:
Perpendicular, because the slopes are opposite (depends on what the answer choices are)
Step-by-step explanation:
I believe the correct answer would be B.) 2 points
Answer:

Step-by-step explanation:
<h2>
<em><u>First</u></em><em><u> </u></em><em><u>case</u></em><em><u>:</u></em></h2>
Sides of a square = 3 cm
Therefore, area of the square = <em>side × side</em>
= 3cm × 3cm

<h2>
<em><u>Second</u></em><em><u> </u></em><em><u>c</u></em><em><u>ase</u></em><em><u>:</u></em></h2>
Radius of the circle = 4cm
Therefore, area of the circle



<h2><em><u>Last</u></em><em><u> </u></em><em><u>case</u></em><em><u>:</u></em></h2>
Area of the shaded region
= <em>Area</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>circle</em><em> </em><em>-</em><em> </em><em>Area</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>square</em><em> </em>


The slope of the line would be 3
Let the length be x
Area = x²
Perimeter = 4x
<span>Area of a square is 3 times its perimeter
</span>⇒ x² = 3(4x)
x² = 3(4x)
x² = 12x
x² - 12x = 0
x(x - 12) = 0
x = 0 or x = 12
Since x cannot be zero, x = 12
Answer: The length is 12 units.
