Area:
The area of a 2D shape is the amount of space inside the shape. It is calculated by multiplying the length of each side of the shape by itself.
Formula: A = Length of Side^2
Example: The area of a triangle with a base of 5 cm and a height of 10 cm is A = 5 cm * 10 cm = 50 cm^2.
Perimeter:
The perimeter of a 2D shape is the total length of all its sides. It is calculated by adding the lengths of all sides of the shape.
Formula: P = Length of Side + Length of Side + Length of Side
Example: The perimeter of a triangle with sides of 3 cm, 4 cm, and 5 cm is P = 3 cm + 4 cm + 5 cm = 12 cm.
Special Cases:
Triangle: For a triangle, the perimeter is equal to the sum of the lengths of any two sides.
Circle: The perimeter of a circle is equal to 2πr, where r is the radius of the circle.
Conclusion:
Area and perimeter are two important concepts in quantitative aptitude that help us understand the size and shape of various 2D shapes. By understanding these concepts, we can easily calculate the area and perimeter of different shapes and apply them to real-world problems
