The length of a rectangle is twice its width.
The perimeter of the rectangle is 42cm

Label the diagram with the correct length and width for the rectangle.

The length of the rectangle is 14 on both sides. The width of the rectangle is 7 on both sides.

Step-by-step explanation:

Take 42 and divide it by 3 and you get 14

divide 14 in half and you get 7

14+14+7+7=42

The length of the rectangle is 14 on both sides. The width of the rectangle is 7 on both sides.

Step-by-step explanation:

Take 42 and divide it by 3 and you get 14

divide 14 in half and you get 7

14+14+7+7=42

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
