What is the altitude of a trapezium, the sum of the lengths of whose parallel sides is 9.5 cm and the area is 57 cm2?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 12 cm
Given:
Sum of parallel sides of trapezium = 9.5 cm
Area of trapezium = 57 cm2
Formula used:
Area of trapezium = (1/2) × (Sum of parallel sides) × altitude ---- (1)
Calculations:
Using equation (1), we get
⇒ 57 = (1/2) × (9.5) × Altitude
⇒ altitude = 6 × 2 = 12 cm
