Answer:
B
Step-by-step explanation:
When you arrange the N points in sequence around the polygon (clockwise or counterclockwise), the area is half the magnitude of the sum of the determinants of the points taken pairwise. The N determinants will also include the one involving the last point and the first one.
For example, consider the vertices of a triangle: (1,1), (2,3), (3,-1). Its area can be computed as
(1/2)*|(1*3-1*2) +(2*-1-3*3) +(3*1-(-1)*1)|
= (1/2)*|1 -11 +4| = 3
Divide the numerator and denominator by their gcf (25)
75/25= 3
100/25= 4
Final answer: 3/4
The rate of change is 4 so your answer would be D. 4
