03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | Perimeter = 38 cm. | Opposite sides of a rectangle are equal, so add 12 and 7 then double it. |
| 2 | Area = 81 cm squared. | The area of a square is the side multiplied by itself. |
| 3 | Volume = 160 cm cubed. | Volume of a cuboid is length times width times height. |
| 4 | Area = 84 cm squared. | Base times perpendicular height, not the slant side. |
| 5 | Area = 72 cm squared. | Base times height, then halve it. |
| 6 | 2.5 m = 250 cm; 3 m squared = 30000 cm squared. | Length is multiplied by 100, but area is multiplied by 100 twice. |
| 7 | Area = 40 cm squared. | Add the two parallel sides, multiply by the height, then halve. |
| 8 | 1.8 L = 1800 mL = 1800 cm cubed. | 1 L is 1000 mL and 1 mL is 1 cm cubed, so the two numbers match. |
| 9 | Surface area = 184 cm squared. | There are three pairs of equal faces, so double the sum of the three products. |
| 10 | The correct value is 40000 cm squared. | Area conversion squares the factor, so multiply by 100 twice, not once. |
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.
Before calculating, decide whether the question gives a length, an area or a volume, because each converts differently. A perimeter is a line in cm, an area is a surface in cm squared, and a volume fills space in cm cubed. Every area formula needs a base and the matching perpendicular height, and a trapezium needs the two parallel sides added before halving. For reverse questions, work backwards from the formula.Tutor Registration →
