1. The mistake that the made was long yards were not the same size

2.area and perimeter are important because the same size has to be the same size.

3.

1.They made the perimeter because 6x2+12x2=32.They can fix the mistake by doing 12x6=72. Also 72 is the answer.2:It is good to know the area and perimeter of something so you know how much it could cost to build or buy the item.

# data[].attributes.body
This student did 6 plus 6 to get the long side but it was actually 12 plus 12 and then for there final answer they would have gotten 56

# data[].attributes.body
they put 36 but its 38 because 12+12=24+6+6=38 not 36

# data[].attributes.body
Area is L x W=Area but they added all them together so the answer is 72

# data[].attributes.body
it equls 48 He added one more 12.So you no when to add the side and the hole thing.

1.This student added the length and width instead of doing length x width.
2.It is important to know about area and perimeter because if you did"nt know then you could not tell where or how big your floor or frame might be if you are getting a new picture or house.
3.

# data[].attributes.body
the person did the added the numbers and got the perimeter but she was spouse to multiply 12x6=24x2= 48

# data[].attributes.body
1

# data[].attributes.body
she used perimeter  instead of area.

we need to know  area and perimeter

# data[].attributes.body
did not do how much you need

1. The student found the perimeter by adding the numbers but the question asks them for the area so 12x6 would get you the answer.
2. Well the student just got the question wrong because they didn't know area and perimeter. Also for when your a adult and if your using a company to build a costume home you need to know how to calculate area and perimeter.
3. You need to know about decimal fraction so when you do fractions just write it in a decimal fraction so it is shorter. And you can't do that if you didn't know the place values and so when you read them you need know what is what.

they did not times they added them together when they were supposed to times then they would get the right answer witch is 76 sand it is not the perimeter. And it is important to learn perimiter because if you need to find out the area it

# data[].attributes.body
What they did was a mistace

# data[].attributes.body
you would multiply 2x12=24 then you would multiply 6x6=36 then you would add 24+36=60 and then that would be perimeter then for area you would just multiply 12x6=72.Why would you need to know perimeter because mabey f you built a house you would need to know what the area and perimeter to make the house.

2. it is important because if you didn't know how to show area and perimiter then if you wanted to become a designer you couldn't because you would have no idea how big anything is.
if you don't know about decimals then you won't now about money.

# data[].attributes.body
The mistake that this person made was that was that they showed the total for the perimeter, not the area.They can fix it by doing length times width,(LxW= __).

# data[].attributes.body
The thing that they did wrong was that they did the perimeter not the area which was what the question was asking.
1. they should fix it by  doing 12 x 6 and that will equal 72 not 36.
2. It is important to know area and perimeter because it is important to know the meaning and the difference between them .

# data[].attributes.body
1. A student made the following mistake. Describe the mistake they made and how they should fix it.

2. Why is it important to know about area and perimeter?

3. Why is it important to know about decimals and place value?
