Question

The two parallel sides of a trapezium are 17 cm and 15 cm, respectively. If the height of the trapezium is 6 cm, then its area (in m²) is:
1. 0.96 m²
2. 0.0096 m2
3. 9.6 m2
4. 960 m2

Answer 1

Correct Answer - Option 2 : 0.0096 m2

Given:

L₁ = 17 cm

L₂ = 15 cm

Height (H) = 6 cm

Concept used:

Area of trapezium = (1/2) × (Sum of parallel side) × Height 

1 cm = (1/100) m 

Calculation:

Let two parallel side be L1 and L2

Area of trapezium = (1/2) × (17 + 15) × 6

⇒ 96 cm²

⇒ 96/10000 m² = 0.0096 m²

∴ The area of the trapezium is 0.0096 m².
