Carla’s vet suggested that her new puppy have at least 64 square feet of exercise space. Carla plans to build an enclosed, square exercise pen in her back yard. How much fencing will she need for this exercise pen?

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )
