The NCERT Class 6 Mathematics Chapter 6 Perimeter and Area Book PDF gives students the official Ganita Prakash chapter for the 2026-27 session. The chapter covers perimeter, area, rectangle and square formulas, grid counting, tangrams, house plans, and area of triangles.
- PDF length: 29 official NCERT pages from the 2026-27 textbook.
- Main focus: boundary length, covered region, and formula use.
- Best use: read each example, then solve the Figure it Out questions.
Student Feedback: In a Collegedunia study poll of 10,980 Class 6 students, most students said Perimeter and Area became easier after they drew the boundary first and shaded the region next. Students also found grid counting helpful before using formulas.

This page hosts the official NCERT Ganita Prakash Chapter 6 PDF, so students can read the same Perimeter and Area chapter used in the 2026-27 classroom.
Perimeter and Area Chapter PDF for Class 6 Students
The Perimeter and Area chapter starts with a simple difference. Perimeter measures the distance around a closed figure. Area measures the space covered by the figure.
- Perimeter is found by adding side lengths.
- Area is found by counting square units or using a formula.
- Every answer needs a unit, such as cm, m, square cm, or square m.

Perimeter Formulas in Class 6 Mathematics Chapter 6
The first part of the PDF revises perimeter formulas for rectangles, squares, and triangles. Students see that a rectangle's opposite sides are equal, so the formula becomes easier to remember.
| Shape | Perimeter Formula | Meaning |
|---|---|---|
| Rectangle | 2 x (length + breadth) | Add length and breadth, then double it. |
| Square | 4 x side | All four sides are equal. |
| Triangle | side 1 + side 2 + side 3 | Add all three side lengths. |
Area of Rectangle and Square in the PDF
The chapter then shifts from boundary to surface. The PDF explains area with grids first, so students can see why a rectangle's area is length multiplied by breadth.
- Rectangle area: length x breadth.
- Square area: side x side.
- Grid method: count complete square units and combine parts carefully.
- Area is written in square units, not plain length units.
Tangrams, House Plans, and Grid Counting
Perimeter and Area uses activities instead of only formulas. Students compare shapes, work with tangram pieces, and read simple house plans to connect textbook formulas with real layouts.
| Activity Type | What Students Practise | Why It Helps |
|---|---|---|
| Grid counting | Counting covered squares. | Builds the idea of area before formulas. |
| Tangram tasks | Comparing pieces made from the same square. | Shows how shapes can change while area is tracked. |
| House plans | Reading room dimensions and floor space. | Connects length, breadth, and area to daily life. |
| Fencing questions | Using perimeter for boundary costs. | Links perimeter to real measurement problems. |
Area of Triangle in Chapter 6
The later part of the chapter introduces area of a triangle through rectangle-based reasoning. Students see that two matching triangles can form a rectangle, so one triangle takes half the rectangle's area.
The useful formula is area of triangle = 1/2 x base x height. The base and height must be perpendicular, so students should mark them before substituting values.
How to Use the Class 6 Mathematics Chapter 6 PDF
Students should keep rough paper beside the PDF. Perimeter and Area is a practice-heavy chapter, so drawing the shape and writing the unit beside each step prevents most mistakes.
- Trace the boundary when the question asks for perimeter.
- Shade the covered part when the question asks for area.
- Use square units only for area answers.
- Try the linked NCERT Solutions after attempting the PDF tasks once.
