Question

The two parallel sides of trapezium are 2.02 meters and 4.04 meters respectively. The perpendicular distance between them is 5 meter. The area of the trapezium is

• A. 30.30 m²
• B. 15.15 m²
• C. 8.16 m²
• D. 66.60 m²

Hint:

Use the standard CI-SI difference-over-two-years relationship to isolate the rate.

Answer 1

The Correct Option is B

The area of a trapezium is found using \(A = \dfrac{1}{2} \times (\text{sum of parallel sides}) \times (\text{height})\).
Substituting the given values: \(A = \dfrac{1}{2} \times (2.02 + 4.04) \times 5 = \dfrac{1}{2} \times 6.06 \times 5 = 15.15\) m².
This straightforward application of the standard formula matches option 2, and it's a good example of how trapezium area problems usually just require careful substitution rather than any complex derivation.
