Perimeter and Area

| 19 Comments

Mr L and Mrs Haran tell me you guys know all about area and perimeter of shapes.

First of all, can you write a definition of what perimeter and area are for me to remember please.

So can you explain exactly what you did to work out your answers?  Please give detailed reasons for why you chose the methods you did. Remember that there may be more than one correct method – so why did you do it like you did?

  1. Perimeter: DISTANCE AROUND THE SHAPE
    Area: SPACE INSIDE THE SHAPE

    Blogsy the rhyme to remember this is…

    Perimeter outside, Area inside

    • That is a very short, simple but accurate definition for Blogsy to use Oliver. Well done

    • The problem below has three answers as far as I’m concerned

      THE WIDTH OF A RECTANGLE IS 2M LESS THAN THE WIDTH
      THE PERIMETER IS BETWEEN 20 AND 30M
      WHAT IS THE LENGTH AND WIDTH OF THE RECTANGLE?

      They are 4 and 6
      And numbers 5 and 7
      Last but not least, 6 and 8

      These are the whole number answers

      SUMSSSSSSS!!!!!!!
      4
      x2 = 8
      +6
      x2
      —————
      20m
      All of

  2. Perimeter is all the sides added together of your shape. So say I had a square measuring 4cm on each side I would need to do the calculation of 4cm +4cm +4cm +4cm.

    Don’t get it mixed up with area witch is the inside of the shape.

  3. the thing you need to remember for perimeter and area is that perimeter is around the outside edge of the shape and the area is the space in the inside of the shape.

  4. The perimeter is the space around the shape mostly use figure out how much carpet they need to cover a space.

    The area is the space inside the shape , mostly people use area to work out how
    many things the size something will fit.

  6. The thing you need to do to find out the perimeter is to use a ruler to measure the out side of a shape and when you have measured all the sides add them together to get the perimeter off the shape.

    To get the area off a shape you need to count the number of squares on the inside of the shape(it is easiest with squared paper).

  7. The thing you need to do to find the perimeter is get a ruler and first measure the outside of the shape maybe if I have a shape that’s 10cm on each top and bottom of a shape then measure the with that could be 8 I would do add 10 +10 and 8+8 toget her it is 36 a quicker way for a square is measure 1 side and multiply it by 4(A x 4)

    The area is the inside an easy way is do it on paper with squares on and the square inside and that,s the area but if you want to do it differently you measure the length once measure the whith times them together you get the area (l x w =the area)

  8. I need to work out this the perimeter of a square of 16 how long is each side of the square?
    . First I figure out how much sides it has the answer is 4
    .Now I find out what 16 Divided by 4=4
    so that’s the answer.

  9. The perimiter of the rectangle is 33m. The width is 3.6m. What is the lenghth.
    3.6m is 3600cm. 33m is 33000cm.

    360
    x 2
    =720

    33000
    – 720
    = 32280

    32280
    / 2
    =16140cm

    The length is 16.140m

    I chose this method beacause it was the easiest I could think of.

  10. problem solving

    1. the perimeter of a rectangle is thirty three centimeters and the height added is 7.2 cm what is the lenght of the triangle?

    Answer = 33-7.2=25.8 25.8/2 =12.9 there it is 12.9!

    reasoning

    1.the perimeter of a square is 16 cm what is the length of each side

    answer= 16/4=4 4 cm

  11. (The perimeter of a square is 16cm. how long is each side?)each side of the square is 4cm long
    first i worked out what number that could equal 16 but also only be added 4 times to make 16 and that number was 4 then i needed to add 4 together 4 times to get my answer(16)

    4+4+4+4=16cm

    (here is a rectilinear shape.all the sides are the same length and are a whole number of centimeters.)

    I think that the perimeter is 36cm long because if you do 3×12=36 and there is 12 sides to this shape so each side is 3 centimeters long.

  12. I like to work out the area of a pizza so I can calculate how much of each of my favourite toppings I need.

    Then I can invite my friends to share the pizza, as long as they like anchovies.
