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

Perimeter

6.3cm 2.1cm 1.2cm 0.8cm Perimeter = = 20.8 Perimeter 2

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 = m 2 AREA 8.5m 2.1m

6.3cm 2.1cm 1.2cm 0.8cm Area = (6.3 x ( )) + (1.2 x 0.8) =(6.3 x 2.9) + (1.2 x 0.8) = = cm 2 Area 2

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

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

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

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

1.2 m 1.1 m 1.4 m Volume = 1.2 x 1.4 x 1.1 = m 3 Volume 2
