**Area and Perimeter 3D Shapes**

Week 6 Maths Area and Perimeter 3D Shapes

2
**Try solving these anagrams – they are all related to Area and Perimeter**

THELNG DITHW RIPMETREE AEAR RELATING

3
**Try solving these anagrams – they are all related to Area and Perimeter**

THELNG = LENGTH DITHW = WIDTH RIPMETREE = PERIMETER AEAR = AREA RELATING = TRIANGLE

4
**Session Aims Define Area and Perimeter**

Calculate Area and Perimeter in a range of 2D shapes Including triangles Understand how to find the Area and Perimeter of compound shapes Test prior knowledge of 3D shapes by: Answering quiz questions Identifying edges, corners, and faces Drawing nets of 3D shapes

5
What is Perimeter? What is Area?

6
What is Perimeter? It is the distance around a 2D shape What is Area?

7
**What is Perimeter? What is Area? It is the distance around a 2D shape**

It is the amount of space inside a 2D shape

8
**Calculating Perimeter**

9
**Calculating Perimeter**

Just add all of the sides together: = 20m

10
Calculating Area 7m 3m 3m 7m

11
Calculating Area 7m 3m 3m 7m Multiply Length by Width: 7 x 3 = 21m²

12
Compound Shapes Compound shapes are really just different rectangles joined together. Just find the area of each part and then add them together.
