Chapter 6 of the Class 6 Maths textbook Ganita Prakash is Perimeter and Area. It covers how to calculate the perimeter and area of basic shapes like rectangles, squares, and simple irregular figures. These Class 6 Mathematics Chapter 6 solutions are also useful as quick revision notes before exams.
What Is Perimeter?
Q: What is the perimeter of a shape, and what units is it measured in?
A: Perimeter is the total distance around the boundary of a closed shape, found by adding the lengths of all its sides. It is measured in units of length, such as cm or m.
Perimeter and Area of a Rectangle
Q: Find the perimeter and area of a rectangle with length 8 cm and breadth 5 cm.
A: Perimeter = 2 × (length + breadth) = 2 × (8+5) = 26 cm. Area = length × breadth = 8 × 5 = 40 sq cm.
Area of a Square
Q: Find the perimeter and area of a square with side 6 cm.
A: Perimeter = 4 × side = 4 × 6 = 24 cm. Area of a square = side × side = 6 × 6 = 36 sq cm.
Area of Irregular Figures
Q: How can the area of an irregular shape drawn on a squared grid be estimated?
A: Count the number of full squares completely inside the shape. For squares that are only partly covered, count two half-covered squares as roughly one full square. Add these together to get an estimated total area.
