The perimeter doesn't tell you the dimensions.
With a 40-ft perimeter, there an infinite number of possibilities
for the length and with. The only thing we know for sure is that

The field could be . . .
1' by 40'
2' by 20'
3' by 13-1/3 '
4' by 10'
5' by 8'
6' by 6-2/3 '
Answer:
A. 400*45.2=400*45+400*0.2=18000+80=18080
B. 14.9*100=15*100-0.1*100=1500-1=1490
C. 76.2*200=76*200+0.2*200=15200+4=15204
Step-by-step explanation:
D=number of dogs
c=cats
d equals 4 less than 2 times c
d=-4+2c
20 dogs
d=20
subsitute
20=-4+2c
add 4
24=2c
divide 2
12=c
12 cats
