Area of Plane Figures
Learning to calculate the area of simple shapes like squares and rectangles.
Core concept
A helpful way to visualise area is by counting how many unit squares (like 1cm × 1cm squares) fit inside a shape — this is literally what the area formula calculates for rectangles and squares. Area has countless practical applications, from calculating how much paint is needed to cover a wall, how much carpet is needed for a room, or comparing the size of two plots of land, making it an essential real-world mathematical skill.

Quick notes
• Area of rectangle = length × breadth; area of square = side².
• Area measures surface covered, in square units (cm², m²), unlike perimeter (linear units).
• Area can be visualised as counting unit squares fitting inside a shape.
• Practical uses: paint needed for a wall, carpet needed for a room, comparing land sizes.
