the perimeter and areas of triangles (using several methods based on information available), quadrilaterals, circles and composite shapes, including arcs
U2.AoS4.11
calculate the perimeter and areas of triangles (calculating the areas of triangles in practical situations using the rules A=1/2 bh, A=1/2 ab sin(c) or A=\sqrt{s(s-a)(s-b)(s-c)} where s=(a+b+c)/2
U2.AoS4.12
use quadrilaterals, circles and composite shapes including arcs and sectors in practical situations
U2.AoS4.13
calculate the perimeter, areas, volumes and surface areas of solids (spheres, cylinders, pyramids and prisms and composite objects) in practical situations, including simple uses of Pythagoras’ in three dimensions
