The lengths of the parallel sides of a trapezium are 10 cm and 20 cm. If the distance between these parallel lines is 5 cm, then what is the area of the trapezium?

50 cm2 60 cm2 45 cm2 75 cm2

75 cm2

We know that, Area of Trapezium = \(\frac{1}{2}\) × (L1 + L2) × height Given, L1 = 10 cm L2 = 20 cm Height = 5 cm Area of Trapezium = \(\frac{1}{2}\) × (L1 + L2) × height = \(\frac{1}{2}\) × (10 + 20) × 5 = 75 cm2
