CBSE 8 Mensuration WorkSheet

Mensuration is the branch of mathematics that deals with the measurement of geometric shapes, such as perimeter, area, and volume.

Perimeter of a Rectangle
- The perimeter of a rectangle is the distance around it.
- Formula: Perimeter = 2 × (Length + Breadth)
Area of a Rectangle
- The area of a rectangle is the amount of space inside it.
- Formula: Area = Length × Breadth
Perimeter of a Square
- The perimeter of a square is the distance around it.
- Formula: Perimeter = 4 × Side
Area of a Square
- The area of a square is the amount of space inside it.
- Formula: Area = Side × Side
Area of a Triangle
- The area of a triangle is the amount of space inside it.
- Formula: Area = (Base × Height) / 2
Circumference of a Circle
- The circumference of a circle is the distance around it.
- Formula: Circumference = 2πr
Area of a Circle
- The area of a circle is the amount of space inside it.
- Formula: Area = πr^2
Surface Area and Volume of 3D Shapes
- The surface area of a 3D shape is the total area of its surface.
- The volume of a 3D shape is the amount of space inside it.
Formulae
- Perimeter of a rectangle: 2 × (Length + Breadth)
