A farmer is installing a new fence. The coordinates of the vertices of the fence are A (2,2), B (2,6), C (8,6), and D (8,2). If each grid square has a length of 9 yards, how much wire is needed for the fence?

a. 20 yards

b. 24 yards

c. 180 yards

d. 216 yards

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
