solve problems involving the area and perimeter of irregular and composite shapes using appropriate units
Elaborations
determining the area of composite shapes by composing or decomposing shapes
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, fertiliser and herbicide are required to cover a paddock
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
