Answer:
Try your best! I know you can do it!
28 divided by 3 is 9.33333333
3 divided by 28 is 0.10714286
Not sure
te rate is r
for decay, it is
A=P(1-r)^t
r=rate
P=present amount
dunno what b is
but I guess
A=28000(1-0.13)^t
A=28000(0.87)^t
I would guess the decay factor would be 0.87
Area= length * height
21*9 = 189cm^2
