Option 1 : 20 m

**Given**

Area of trapezium is 440 m^{2}

Lengths of parallel sides are 30 m and 14 m

**Concept:**

Area of trapezium = (1/2) × ( Sum of the parallel sides ) × height

**Calculation:**

440 = (1/2) × (30 + 14) × height

⇒ 440 = (1/2) × 44 × height

⇒ 440 = 22 × height

⇒ Height = 440/22 = 20

⇒ Height = 20 m

**∴ Height = 20 m**
