Transcript of "Area and perimeter"

  1. 1. Area and Perimeter TOBY’S LESSON ON......
  2. 2. The distance around the outside of a shape is called the perimeter. 8 cm 6 cm 8 cm 6 cm The perimeter of the shape is 8 + 6 + 8 + 6 = 28cm. First we need to find he length of each side by counting the squares.
  3. 3. 18cm 18cm 18cm 22cm 26cm What is the perimeter of each of these shapes? Your teacher will give you copy of the worksheet.
  4. 4. Now find the perimeter of these shapes. They are not drawn to scale. Perimeter = 18cm Perimeter = 22cm Perimeter = 28cm 3cm 3cm 3cm 3cm 3cm 3cm 5cm 7cm 7cm 3cm 4cm 4cm 4cm 4cm 3cm 3cm 3cm 3cm
  5. 5. The area of a shape is the amount of space inside it. The area of the shape is 18cm 2 . To find out how much shape is inside we can count the squares.
  6. 6. 12cm 2 26cm 2 26cm 2 What is the area of each of these shapes? Your teacher will give you copy of the worksheet.
  7. 7. To find the area of an irregular shape you first count the full squares inside it. This is an irregular shape. This means that the sides aren’t straight.
  8. 8. The area of the shape is 60cm 2 . You then count all the other squares which have more than half the area covered.
  9. 9. 24cm 2 25cm 2 22cm 2 35cm 2 What is the area of each of these shapes? Your teacher will give you copy of the worksheet.
  10. 10. The area of the shape is 48cm 2 . The rectangle is made of 6 rows of 8 squares. To work out the number of squares we times 6 by 8. Counting each square can take a long time. Does anyone know a quicker way?
  11. 11. What is the area of each of these shapes? Your teacher will give you copy of the worksheet. 20cm 2 18cm 2 14cm 2 30cm 2 22cm 2
  12. 12. We can work out the area of a rectangle without the grid. length width Area = length x width
  13. 13. Now work out the area of these rectangles. They are not drawn to scale . 36cm 2 35cm 2 20cm 2 25cm 2 4cm 9cm 7cm 5cm 5cm 4cm 2cm 12.5cm
  14. 14. A shape that is made from other shapes is known as a composite shape. To find the area of this shape we have to split it up into two rectangles. 10cm 8cm 8cm 2cm 4cm 4cm Area = 4 x 10 40cm 2 Area = 4 x 8 32cm 2 Total area = 40 + 32 = 72 cm 2
  15. 15. Find the area and perimeter of each of these shapes? Your teacher will give you copy of the worksheet. 9cm 5cm 5cm 2cm 4cm 5cm 4cm 2cm 11cm 7cm 4cm 3cm 3cm 3cm 7cm 4cm 6cm 6cm 11cm 2cm 4cm 5cm
  16. 16. 9cm 5cm 5cm 2cm 4cm 5cm 4cm 2cm Area = 5 x 9 45cm 2 Area = 4 x 5 20cm 2 Total area = 45 + 20 = 65 cm 2 Perimeter = 36 cm
  17. 17. Area = 2 x 5 10cm 2 Area = 6 x 6 36cm 2 Total area = 10 + 36 = 46 cm 2 Perimeter = 34 cm 6cm 6cm 11cm 2cm 4cm 5cm
  18. 18. 11cm 7cm 4cm 3cm 3cm 3cm 7cm Total area = 28 + 16 + 21 = 65 cm 2 Perimeter = 42 cm Area = 4 x 7 Area = 4 x 4 4cm Area = 3 x 7 21cm 2 28cm 2 16cm 2 There is another way of doing this question.
  19. 19. 11cm 7cm 4cm 3cm 3cm 3cm 7cm Total area = 77 – 12 = 65 cm 2 Perimeter = 42 cm Area = 7 x 11 Area = 3 x 4 4cm 77cm 2 12cm 2
