WAL how to find the perimeter and area of some classroom objects.

Term 4

OBJECT | PERIMETER | AREA |

Formula | P= 2 (L + B) mm,cm,m | A = L x B/W (sq mm,sq cm,sq m) |

Maths book | L=25 sq cm B=20 sq cm P=45 sq cm | L= 25 sq cm B =20 sq cm A =500 sq cm |

Modelling book | L=40 sq cm B=30 sq cm P=70 sq cm | L=40 sq cm B=30 sq cm A=1200 sq cm |

Large Rectangular Table | L=120 sq cm B=80 sq cm P=200 sq cm | L=120 sq cm B=80 sq cm A=1600 sq cm |

Tote tray | L=40 cm B=25 sq cm P=65 sq cm | L=40 sq cm B=25 sq cm A=1000 sq cm |

Learning Reflection

I found this hard because I did not understand how to do the area

and it took a long time to figure out the answer and I found getting the answer for the perimeter easy because you just had to measure the perimeter and you had to add them together.
