A = 28000(0.9275)^5
a = 19219
$19,219 is the answer
Hoped this helped
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
By minusing 12 to both sides
d+12=2
-12=-12
d =-10

Omg it is so hard i think it is 60 maybe idk Ф∞∨≥,,
