Area of Parallelograms
A parallelogram has two pairs of parallel sides. Its area is base × height. Do not use the slanted side — use the perpendicular height!
Your goals
- ✓You can calculate the area of parallelograms.
- ✓You can use parallelogram, perpendicular height correctly.
- ✓You can multiply the base by its perpendicular height.
Words to know
- parallelogram:
- A quadrilateral with two pairs of parallel opposite sides.
- perpendicular height:
- The shortest distance between the chosen base and the opposite side.
Examples
- 1Base 12 cm, height 5 cm: Area = 12 × 5 = 60 cm²
- 2Base 7 cm, height 9 cm: Area = 7 × 9 = 63 cm²
Check these
- • Do not use the sloping side instead of the perpendicular height.
- • Keep every number, symbol, label, and unit in its correct place.
- • Show enough working to check how you reached your answer.
Helpful habits
- • Read the whole question before choosing what to do.
- • Show one clear step at a time and check each step.
- • If you are stuck, draw a model, try smaller numbers, or revisit the example.
