  1. Challenge 3
    The value of the circle is 30
    The value of the triangle is 50
    The value of the square is 20
    Challenge 4
    The perimeter of the shape is 98cm
    14cmx7cm=98cm
    Challenge 4
    The shirt costs £56 since that is £25 more than the shirt
    87-25=62
    62/2=31
    31+25=56

  2. Challenge 3
    70+30=100
    50+50+100
    30+50+20=100

    Challange 4
    42cm/6=7cm
    7cmx14=98cm is the perimeter.

    Challenge 4
    £87/2=£43.50.
    £43.50+£25=£68.50.
    The jacket cost is £86.50
    The shirt cost is £18.50.

    • Great job Esa, well done! Try challenge 4 again. You have found the perimeter of one heptagon however you need to find the perimeter of the whole shape.

  3. Challenge 3
    70+30=100
    50+50=100
    60+30+10=100
    Challenge 4
    4 hexagon =168cm
    Challenge 4
    87-25=62
    62÷2=31
    31+25=56
    The market cost £25 and the shirt £56

  4. Challenge 3
    70 + 30 = 100 ( The value of the red circle is 30).
    50 + 50 = 100 ( The value of the green triangle is 50 ).
    30 + 50 + 20 = 100
    So the value of the blue square is 20.
    ————————————–
    Challenge 4
    One side of the hexagon = 42/6 = 7 cm
    The perimeter of the new shape is = 14 cm x 7 cm = 98 cm.
    ————————————-
    Challenge 4
    £87 – £25 = £62
    £62/ 2 = £31 the price of the shirt.
    The price of the jacket = £31 + £25 = £56.

  5. Challenge 3:

    The value of the square is 20
    This is because 70+30=100 (circle =30)
    50+50=100 (triangle =50)
    Therefore the square is 20 (30+50+20=100)

    Challenge 4:

    The perimeter of a regular hexagon is 42cm
    To find one side you have to divide by 6 because there’s 6 sides.
    42 divided by 6=7
    Each side on a hexagon is 7cm
    7×14=98cm
    You have to times 7 by 14 as there are 14 exterior sides.
    Total perimeter=98cm

    Challenge 5:

    87-25=62
    62 divided by 2= 31
    31+25=56
    Therefore the jacket is £56 and the shirt is £31

    • Brilliant. You really explained your answer perfectly. You’ll do great in year 4.
      Well done for all your work. Have a lovely summer break, see you around in September 👍.

  6. Challege 3.
    70 +30 =100.
    50 + 50 = 100.
    30 circle +50 triangle +20 square =100.
    Challege 4.
    The cost of the jacket is £56 this is £25.
    87 – 25 =62.
