WORKSHOP CALCULATION - CITS
The Determination of areas, perimeters of triangles, quadrilaterals, polygons, circle, sector etc.
Basic Geometry Formulas
• Perimeter of a Square = 4(Side)
• Perimeter of a Rectangle = 2(Length + Breadth)
• Area of a Square = Side 2
• Area of a Rectangle = Length × Breadth.
• Area of a Triangle = ½ × base × height.
• Area of a Trapezoid = ½ × (base1 + base2) × height.
• Area of a Circle = A = π×r 2
• Circumference of a Circle = 2πr.
Mensuration 3D: Determination of volumes, surface areas of cube, cuboids cylinders, hollow cylinder,
sphere prisms, pyramids cone spheres, frustums etc.
