What is the area of the figure at the right. justify your procedure?

The area of the smaller figure would be found by multiplying its base length by its height. The height is explicitly provided while the base length is not.

To find the base length of the smaller figure, subtract the shorter length on the bottom (3.1 inches) from the total length on top (6.1 inches).

6.1 - 3.1 = 3

3 * 3 = 9

The area of the figure at the right is 9 square inches.

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
