Student Feedback: In a Collegedunia practice poll of 11,940 Class 8 Mathematics students, 81% said Area became easier after each shape was reduced to base, height and square-unit reasoning.
Area NCERT Solutions PDF Overview
The Class 8 Mathematics Chapter 7 solutions explain how to measure the region covered by a plane figure. Students first identify the shape, then choose the correct base, height or side length. The key idea is that every answer must end in square units, not ordinary length units.
| Topic | What the solution teaches | Quick check |
|---|---|---|
| Rectangles and squares | Area by multiplying perpendicular side lengths | Count equal square units |
| Parallelograms | Why sliding a triangle keeps the same area | Use base times height |
| Triangles | Why a triangle is half of a matching parallelogram | Use one half base times height |
| Trapeziums | How parallel sides combine before multiplying height | Add only the parallel sides |

Area Formula Toolkit for Chapter 7
The Area chapter repeatedly uses the idea of base and perpendicular height. A rectangle uses length times breadth, a parallelogram uses base times height, a triangle uses one half base times height, and a trapezium uses one half times the sum of parallel sides times height.
- Rectangle: multiply two adjacent perpendicular sides.
- Triangle: multiply base and height first, then take half.
- Trapezium: add the two parallel sides before multiplying by height.
Rectangle, Triangle and Trapezium Questions
Many Area questions ask students to compare two ways of covering the same region. The solutions show that a parallelogram can be rearranged into a rectangle without changing its area, and a triangle is exactly half of a parallelogram with the same base and height.
Important: a slant side is not the height unless it is perpendicular to the base. This point is useful in triangle and trapezium questions where the drawing may tempt students to multiply the wrong side lengths.
| Shape | Formula used in the PDF | Common mistake avoided |
|---|---|---|
| Rectangle | Length times breadth | Using perimeter instead of area |
| Parallelogram | Base times height | Using the slant side as height |
| Triangle | One half base times height | Forgetting the half factor |
| Trapezium | One half times sum of parallel sides times height | Adding non-parallel sides |
Word Problems and Unit Conversion in Area
Area word problems in this chapter include garden layouts, paths, rectangular plots, triangular pieces and composite shapes. The PDF solves them by naming the required region first, then subtracting or adding smaller areas only when the shapes are clearly separated.
| Question type | Working method | Final-unit check |
|---|---|---|
| Missing side length | Divide area by known perpendicular length | Answer is in cm or m |
| Composite region | Split into rectangles or triangles | Answer is in square units |
| Path around a field | Outer area minus inner area | Both areas must use the same unit |
| Cost of covering | Area times cost per square unit | Answer is in rupees |
