Mensuration Of 2D Shapes
Gbogbo ọrọ náà
Mensuration is the branch of mathematics concerned with measuring lengths, areas and volumes. In two dimensions you need to find perimeters (the distance around a shape) and areas (the space inside a shape) for triangles, rectangles, parallelograms, trapezia, circles, semicircles and compound shapes built from these.
This topic also requires you to convert fluently between metric units for both length and area. Higher-tier students extend circle work to arc lengths and sector areas. These skills appear across both papers and connect directly to 3D mensuration and trigonometry.
