The concepts of perimeter and area are fundamental in geometry and are used in various real-life applications such as construction, design, and land measurement.
The perimeter of a shape is the total length of its boundary. It is measured by adding up the lengths of all sides.
Example 1: Find the perimeter of a rectangle with length 10 cm and breadth 5 cm.
Perimeter = 2 × (10 + 5) = 2 × 15 = 30 cm
Area is the amount of surface covered by a shape. It is measured in square units.
Example 2: Find the area of a square with side length 4 cm.
Area = 4 × 4 = 16 cm²
Understanding perimeter and area is essential for solving many practical problems. These concepts are widely used in architecture, land management, and everyday measurements.
