1. 216m

2. 224cm

3. 90m

4. 40in

Step-by-step explanation:

l x w x h

4.5m x 6m x 8m = 216m

same for the other 3 questions

sorry i don't understand the other page

hope that helps

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

the correct is answer is a 9-sided polygon!
