Correct Answer - Option 3 : 18 cm
Given:
The area of a trapezium = 540 cm2
The length of its parallel sides are 35 cm and 25 cm
Formula Used:
Area of trapezium = 1/2 × Sum of parallel sides × Height
Calculation:
Area of trapezium = 1/2 × Sum of parallel sides × Height
⇒ 540 = 1/2 × (35 + 25) × Height
⇒ Height = 18 cm
∴ The perpendicular distance between parallel side is 18 cm.
