Perimeter and Area
NCERT Ganita Prakash for Class 6, Chapter 6, Perimeter and Area, begins with walking the boundary of a park and covering the ground with mats. It defines perimeter as the total boundary length of polygons measured with thread and ruler, and area as unit squares covering a surface. It derives the area of rectangles and squares from rows and columns, halves a rectangle to find a right triangle, and converts between square centimetres, square metres, and larger units through fencing and flooring tasks.
