Students learn how to find the perimeter and area of various 2D shapes including triangles, quadrilaterals, compound shapes and circles. Throughout the topic links are made to algebraic reasoning and estimation. This topic takes place in Term 4 of Year 9 and links to arc length and area of sectors later on.
