Study Notes
What is Mensuration?
- Mensuration is the branch of mathematics that deals with the measurement of geometric quantities such as length, area, and volume of various shapes.
Types of Mensuration
- Plane Mensuration: Deals with the measurement of geometric quantities of two-dimensional shapes such as triangles, quadrilaterals, polygons, and circles.
- Solid Mensuration: Deals with the measurement of geometric quantities of three-dimensional shapes such as cubes, cuboids, spheres, and cylinders.
Key Concepts
- Perimeter: The distance around a shape.
- Area: The size of a shape's surface.
- Volume: The amount of space inside a shape.
- Circumference: The distance around a circle.
Formulas
-
Triangle:
- Area: (base × height) / 2
- Perimeter: a + b + c (where a, b, and c are the sides)
-
Circle:
- Area: π × radius²
- Circumference: 2 × π × radius
-
Rectangle:
- Area: length × width
- Perimeter: 2 × (length + width)
-
Cuboid:
- Volume: length × width × height
- Surface Area: 2 × (length × width + width × height + height × length)
Real-World Applications
- Architecture: Mensuration is used to calculate the area and volume of buildings and rooms.
- Engineering: Mensuration is used to calculate the size and shape of bridges, tunnels, and other structures.
- Design: Mensuration is used to calculate the area and shape of objects and spaces.
