The lengths of a pair of parallel sides of a trapezium are 20 cm and 25 cm, respectively, and the perpendicular distance between these two sides is 14 cm. What is the area (in cm2 ) of the trapezium?
Answer & explanation
Correct answer: option 4
We know that,
Area of trapezium = \(\frac{1}{2}\) × Sum f the parallel sides × Perpendicular distance between the parallel sides
Now,
Area = \(\frac{1}{2}\) × (20 + 25) × 14 = 45 × 7 = 315 cm²
