  1. Subject - Mathematics Topic – Perimeter CLASS – V -B PREPARED BY – ANIL KUMAR K.V.P.L MEERUT CANTT

  2. IRREGULAR SHAPES

  3. REGULAR SHAPES TRIANGLE SQUARE RECTANGLE PENTAGON OCTAGON HEXAGON

  4. Boundary

  5. The total distance around the outside of a shape is called boundary/PERIMETER. First we need to find its length of each side by counting the squares. 1 side of sq. = 1 cm 8 cm 6 cm 6 cm 8 cm The total distance around of the shape is 8 + 6 + 8 + 6 = 28cm.

  6. 4cm 4cm 5cm 3cm 3cm 3cm 3cm 3cm 7cm 7cm 3cm 3cm 3cm 3cm 4cm 4cm 3cm 3cm Now find the perimeter of these shapes. They are not drawn to scale. Perimeter = 18cm Perimeter = 22cm Perimeter = 28cm

  7. 18cm 18cm What is the perimeter of each of these shapes? 22cm 18cm 26cm

  8. Finding the Perimeter

  9. 16 cm Take a walk around the edge of this ground ! 6 cm 10 cm The perimeter is… KV PUNJAB LINES PLAY GROUND 6 + 10 + 6 + 10 = 6cm 32cm ! 32 cm 22 cm

  10. Take a walk around the edge! 8 The perimeter is… 8 + 8 + 10 = 8cm 26 8cm 26 cm ! 16 10 cm

  11. 12 16 Take a walk around the edge! This is a regular octagon with sides 4 cm 20 8 The perimeter is… 4 32 cm ! 24 32 28

  12. 30 Take a walk around the edge! This shape has sides of 5 cm each The perimeter is… 15 60 cm ! 45 60
