Area and Perimeter of Shapes
LO: I know how to find the perimeter and area of 2d shapes
I can find the area of a square, rectangle, and triangle using a formula

3. Area of a rectangle PERIMETER = distance around the shape
AREA = length x width
8cm
4cm

4. Area of a rectangle Work out the perimeter and area of the following:
9cm
8cm
4cm
7cm
8cm
5cm
7cm
18cm
6cm
8cm
12cm
6cm

5. Area of a rectangle
Missing length = area ÷ length
8cm
A = 40cm2

6. Area of a rectangle Work out the missing lengths: 10cm 8cm A = 40cm2

7. Area of a triangle
AREA = base x vertical height 2
5cm
9cm

8. Area of a triangle

9. Area of a parallelogram
AREA = base x perpendicular height 6m 8m

10. Area of a parallelogram
AREA = base x perpendicular height

12. Area
Nod y Wers: Am I able to calculate the area of compound shapes?
Level: 6
Starter: recap

Compound shapes – split the shape into other shapes with lengths that you are given / can work out.
22cm
8cm
10cm
