Answer 1

C

Explanation:

Answer 2

find the disatnces from
A to B
from B to C
from C to D
fom D to A



AB, (2,2) to (2,6)
notice x didn't change
from 2 to 6 is 4
AB=4

BC, (2,6) to (8,6)
notice y didn't change
from 2 to 8 is 6
BC=6

CD, (8,6) to (8,2)
notice x didn't change
from 6 to 2 is distance of 2
CD=2

DA, (8,2) and (2,2)
notice y didn't change
from 8 to 2 is distance of 6
DA=6


AB+BC+CD+DA=
4+6+4+6=
10+10=
20
20 units
each is 9 yards legtngh

20*9=180

180 yards needed
C is answer
