What the chapter is about
This chapter is about a grandmother's quilt — a warm cover made by stitching many small pieces of cloth together. Each piece has its own colour and story.
A quilt is also a maths lesson in area and patterns. To know how much cloth is needed, we find the area: a rectangle's area = length × breadth. A quilt made of 10 rows with 8 pieces in each row has 80 pieces.
The chapter celebrates love and patience: a quilt takes weeks to make, and every stitch carries the grandmother's care for her family.
Area also tells us how much material a job needs — cloth for a quilt, paint for a wall, or tiles for a floor. That is why area is measured in square units: we are counting how many small squares cover a surface.
What you should learn
Area answers 'how much surface?' — count squares or multiply length × breadth. Do not confuse area with perimeter (the boundary).
Key Terms
- Quilt — A warm cover made of stitched cloth pieces.
- Area — The surface covered by a shape.
- Perimeter — The distance around a shape.
- Patch — One small piece of cloth in a quilt.
- Rectangle — A shape with 4 sides and 4 right angles.
- Square unit — A unit used to measure area, such as one small square of side 1 cm.
Remember
- Area of rectangle = length × breadth.
- Perimeter = sum of all sides.
- Area is measured in square units.
- A quilt's pieces form rows and columns — multiply to count.
Exam Tip / Common Mistake
Common mistake: mixing area and perimeter. Area covers the inside (square units); perimeter walks around the outside (ordinary units).
Chart / Table: Area vs perimeter
| Measure | Meaning |
|---|---|
| Area | Surface inside the shape |
| Perimeter | Distance around the shape |
| Area unit | square cm |
| Perimeter unit | cm |
Think and try
Draw a rectangle 6 cm long and 4 cm wide on squared paper. Count the squares inside it. Does your count match 6 × 4? Why does counting squares give the same answer as multiplying?
Practice set — try it yourself
- A quilt has 12 rows with 9 patches each. How many patches?
Hint: Multiply rows by patches. - Find the area of a rectangle 8 cm long and 5 cm wide.
Hint: Multiply length by breadth. - Find the perimeter of a square with side 6 cm.
Hint: Add all four sides. - A mat is 10 cm by 4 cm. What is its area?
Hint: Multiply. - Draw a rectangle with area 12 square cm.
Hint: Find two numbers that multiply to 12.
