Lesson plan
Area and perimeter of
rectilinear shapes and
compound shapes
1. Lesson objectives
• Explore the area and perimeter of squares, rectangles, triangles and compound
shapes
• Understand the concepts of area and perimeter and use them in a range of
problem-solving situations
2. GCSE curriculum
Geometry and measures
G14 use standard units of measure and related concepts (length, area,
volume/capacity, mass, time, money, etc.)
G16 know and apply formulae to calculate area of triangles, parallelograms, trapezia;
volume of cuboids and other right prisms (including cylinders)
G17 know the formulae: circumference of a circle = 2πr = πd, area of a circle = πr

;
calculate: perimeters of 2D shapes, including circles; areas of circles and composite
shapes; surface area and volume of spheres, pyramids, cones and composite solids
