Parallel side of a trapezium are 21 cm and 14 cm and its area is 875 cm2. What us the distance between parallel sides ?
Answer & explanation
Correct answer: option 2
We know that,
Area of trapezium = \(\frac{1}{2}\) × (sum of parallel sides) × (distance between parallel sides)
we have,
Sides = 21 cm, 14 cm
Area = 875 cm2
875 = \(\frac{1}{2}\) × (21 + 14) × distance
875 × 2 = 35 × distance
Distance = 25 × 2 = 50 cm
