1. Perimeter, Area and Volume Presented by Bill Haining Functional Skills L1

2. Perimeter

3. 6.3cm 2.1cm 1.2cm 0.8cm Perimeter = 6.3 + 2.1 + 1.2 + 0.8 + 1.2 + 6.3 + 0.8 + 2.1 = 20.8 Perimeter 2

4. What is the area of a shape? How much flat space it takes up. How do you calculate the area? Area = length x width = 8.5 x 2.1 = 17.85 m 2 AREA 8.5m 2.1m

5. 6.3cm 2.1cm 1.2cm 0.8cm Area = (6.3 x (2.1+0.8)) + (1.2 x 0.8) =(6.3 x 2.9) + (1.2 x 0.8) = 18.27 + 0.96 = 19.23 cm 2 Area 2

6. What is the area of a triangle? A triangle is half of a rectangle so the area of a triangle is: ½ x base x height Area 3

7. 1.2 m 3.1 m Area = ½ x 3.1 x 1.2 = 1.86 m 2 Area 4

8. 1.5 m 1.2 m Area = ½ x 1.2 x 1.5 = 0.9 m 2 Area 5

9. What is the volume of a 3-D shape? The total amount of space it takes up. How do we calculate the volume of a cuboid? Length x depth x height Volume

10. 1.2 m 1.1 m 1.4 m Volume = 1.2 x 1.4 x 1.1 = 1.848 m 3 Volume 2
