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?
Answer & explanation
Correct answer: option 4
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
