Geometry and TrigonometryEasy–MediumHeight of a parallelogram from its area
Geometry and Trigonometry practice question
A parallelogram has an area of 48 square centimetres and a base of 8 centimetres. What is its height, in centimetres?
Answer: 6
Area = base × height, so 48 = 8h and h = 6.
Common wrong answers
- If you answered 3
- 3 halves the correct height; there is no 1/2 in a parallelogram's area.
- If you answered 12
- 12 comes from 48 = (1/2)(8)h, using the triangle formula; a parallelogram uses the full product.
- If you answered 40
- 40 is 48 − 8, subtracting instead of dividing.
