AC9M8M01

See also: Learning Areas / Mathematics / Mathematics / Measurement / Year 8

solve problems involving the area and perimeter of irregular and composite shapes using appropriate units

Elaborations

• AC9M8M01_E1 - determining the area of composite shapes by composing or decomposing shapes
• AC9M8M01_E2 - using arrays and rectangles to approximate the area of irregular shapes in situations such as a council needing to work out how much mosquito spray to use for a swamp area or a farmer needing to work out how much seed, fertilizer and herbicide are required to cover a paddock
• AC9M8M01_E3 - determining the perimeter and area of irregular shapes by sums of increasingly accurate covering measurements, such as line segments and grids; for example, using millimetres or square millimetres as opposed to centimetres or square centimetres

Achievement Standard Components

• ASMAT809 - Students use appropriate metric units when solving measurement problems involving the perimeter and area of composite shapes, and volume of right prisms.
