The length of a rectangle is 12 cm.
What is the width if the area is 72 cm?

Width of the rectangle = 6cm

Step-by-step explanation:

Let width be b

Area of rectangle = 72cm²

length× width = 72cm²

12×b= 72

b= 72/12

b= 6cm

Width = 6 cm.

Step-by-step explanation:

The formula for are is length x width. You have the length, which is 12. This gives you this equation...

12 x ? = 72 cm.

If you use the inverse operation (opposite) of multiplication, you divide both sides by 12, giving you 6 cm. To double check, do 6 x 12, which equals 72.

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
