Mensuration Of 2D Shapes
Muhtasari
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.
Malengo
- Convert measurements within the metric system to include linear and area units
- Find the perimeter of shapes made from triangles and rectangles
- Find the area of simple shapes using the formulae for the areas of triangles and rectangles
- Find the area of parallelograms and trapezia
- Find circumferences and areas of circles using relevant formulae; find perimeters and areas of semicircles
- [Higher] Find perimeters and areas of sectors of circles
