CIE IGCSE Mathematics Workbook: Mensuration – Units, Area, Circles, Solids & Compound Shapes

Topics Covered:
This workbook guides students through five essential areas of mensuration:

• Units: Convert between different measurement units with ease.

• Perimeter & Area: Learn to calculate the perimeter and area of common 2D shapes.

• Circles: Master circumference and area calculations for circles.

• 3D Shapes: Find the volume and surface area of solids.

• Compound Shapes: Solve complex problems involving mixed shapes.

Key Formulas to Remember:

• Area of a circle: πr2\pi r^2πr2

• Circumference of a circle: $2\pi r$

• Area of a triangle: 12×base×height\frac{1}{2} \times \text{base} \times \text{height}21​×base×height

• Area of a rectangle: length × width

• Volume of a cube: side³

• Volume of a cylinder: πr2h\pi r^2 hπr2h

Units Conversion Examples:

• 1 m = 100 cm

• 1 km = 1000 m

• 1 m² = 10,000 cm²

• 1 m³ = 1,000,000 cm³

Why This Workbook is Important:
Mensuration has real-world applications in:

• Construction: Calculating materials for building.

• Engineering: Designing structures.

• Everyday Life: Measuring for home improvement or cooking.
