The point proportion of defective units is 2/40 = 0.05
It would be: 20- 20*20/100 = 20-4 = $16

The proof that the diagram is a square is that; D: slopes are perpendicular where the sides meet
<h3>How to Prove a quadrilateral is a Square?</h3>
We know that a square is a quadrilateral that has 4 sides. Now, the 4 sides of a square are all equal and at right angles.
Since all sides of the square are equal, then it means that 2 consecutive sides must be perpendicular to each other. Thus, this means that the slope of 2 consecutive sides must be perpendicular to each other.
