Class 6 Maths - ODISHA
Perimeter and Area
In the 'Perimeter and Area' chapter for Class 6 Odisha Board (BSE), students learn to measure the boundary and the inner region of closed flat shapes. This chapter builds a strong foundation in geometry by teaching how to calculate the distance around figures like rectangles and squares, as well as the surface space they occupy using standard units. These concepts are very important for the BSE Odisha Class 6 Mathematics examinations, frequently appearing in both short answer questions and practical word problems that test everyday measurement skills.

Perimeter
The total length of the boundary enclosing a closed plane figure, calculated by adding the lengths of all its sides together.
Area
The amount of surface enclosed within a closed boundary figure, measured in square units.
Perimeter of a Rectangle
Twice the sum of its length and breadth, since opposite sides of a rectangle are equal.
Area of a Square
The product of the side of the square multiplied by itself, as all four sides are of equal length.
Units of Measurement
Perimeter is measured in linear units like centimeters (cm) or meters (m), while area is always measured in square units like square centimeters (cm²) or square meters (m²).

Board Exam Info
In the BSE Odisha Class 6 Mathematics examinations, this chapter typically carries around 8 to 12 marks. Common question types include direct formula-based calculations, word problems about fencing a garden (perimeter) or carpeting a floor (area), and drawing figures on graph paper to find their area.
Frequently Asked Questions
What is the difference between perimeter and area?
Perimeter is the total length around the outer edge or boundary of a shape, while area is the total space or region covered inside that boundary.
Why do we write square units for area?
We write square units (like cm² or m²) because area is calculated by multiplying two dimensions (length and breadth), using small squares as a standard measuring tool.
Can two different shapes have the same perimeter but different areas?
Yes, two shapes can have identical total boundary lengths (perimeter) while enclosing different amounts of inner space (area).
