03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 40 sq cm | Count the squares: 8 x 5 = 40 squares, so the area is 40 sq cm. |
| 2 | 36 sq cm | Area of a square = side x side = 6 x 6 = 36 sq cm. |
| 3 | 26 cm | Perimeter = (length + width) x 2 = (9 + 4) x 2 = 26 cm. |
| 4 | 6 cm | Width = area ÷ length = 48 ÷ 8 = 6 cm. |
| 5 | 64 sq cm | Side = 32 ÷ 4 = 8 cm, so the area is 8 x 8 = 64 sq cm. |
| 6 | 20000 sq cm | One square metre is 100 cm x 100 cm = 10000 sq cm, so 2 sq m is 20000 sq cm. |
| 7 | 68 sq cm | The big rectangle is 80 sq cm and the corner is 12 sq cm, so 80 – 12 = 68 sq cm remains. |
| 8 | area 50 sq cm, perimeter 30 cm, 10 cm less | The rectangle is 10 cm by 5 cm: area 50 sq cm, perimeter 30 cm, against 40 cm for the two squares, so 10 cm is lost where they touch. |
| 9 | 1 sq cm | The rectangle is 6 cm by 4 cm with area 24 sq cm; the square has side 5 cm and area 25 sq cm, a difference of 1 sq cm. |
| 10 | area 21 sq cm, perimeter 20 cm | (7 + 3) x 2 gives the perimeter, 20 cm; the area is 7 x 3 = 21 sq cm. Area and perimeter have different units. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
